fix: remove unnecessary user lookup in agent API calls (#17934)

This PR optimizes the agent API by using the `workspace.OwnerUsername` field directly instead of making an additional database query to fetch the owner's username. The change removes the need to call `GetUserByID` in the manifest API and workspace agent RPC endpoints.

An issue arose when the agent token was scoped without access to user data (`api_key_scope = "no_user_data"`), causing the agent to fail to fetch the manifest due to an RBAC issue.

+Hi Bobby,
+
+Workspace my-workspace was claimed from a prebuilt workspace by prebuilds-c=
+laimer.
+
+During the claim, Terraform destroyed and recreated the following resources
+because one or more immutable attributes changed:
+
+docker_container[0]  was replaced due to changes to env, hostname
+
+When Terraform must change an immutable attribute, it replaces the entire r=
+esource.
+If you=E2=80=99re using prebuilds to speed up provisioning, unexpected repl=
+acements will slow down
+workspace startup=E2=80=94even when claiming a prebuilt environment.
+
+For tips on preventing replacements and improving claim performance, see th=
+is guide (https://coder.com/docs/admin/templates/extending-templates/prebui=
+lt-workspaces#preventing-resource-replacement).
+
+NOTE: this prebuilt workspace used the particle-accelerator preset.

+        <p>Hi Bobby,</p>
+        <p>Workspace <strong>my-workspace</strong> was claimed from a prebu=
+ilt workspace by <strong>prebuilds-claimer</strong>.</p>
+
+<p>During the claim, Terraform destroyed and recreated the following resour=
+ces<br>
+because one or more immutable attributes changed:</p>
+
+<ul>
+<li>_docker<em>container[0]</em>  was replaced due to changes to <em>env, h=
+ostname</em><br>
+</li>
+</ul>
+
+<p>When Terraform must change an immutable attribute, it replaces the entir=
+e resource.<br>
+If you=E2=80=99re using prebuilds to speed up provisioning, unexpected repl=
+acements will slow down<br>
+workspace startup=E2=80=94even when claiming a prebuilt environment.</p>

+<p>For tips on preventing replacements and improving claim performance, see=

+# Prebuilt workspaces
+
+Prebuilt workspaces allow template administrators to improve the developer experience by reducing workspace
+creation time with an automatically maintained pool of ready-to-use workspaces for specific parameter presets.
+
+The template administrator configures a template to provision prebuilt workspaces in the background, and then when a developer creates
+a new workspace that matches the preset, Coder assigns them an existing prebuilt instance.
+Prebuilt workspaces significantly reduce wait times, especially for templates with complex provisioning or lengthy startup procedures.
+
+Prebuilt workspaces are:
+
+- Created and maintained automatically by Coder to match your specified preset configurations.
+- Claimed transparently when developers create workspaces.
+- Monitored and replaced automatically to maintain your desired pool size.
+
+## Relationship to workspace presets
+
+Prebuilt workspaces are tightly integrated with [workspace presets](./parameters.md#workspace-presets-beta):
+
+1. Each prebuilt workspace is associated with a specific template preset.
+1. The preset must define all required parameters needed to build the workspace.
+1. The preset parameters define the base configuration and are immutable once a prebuilt workspace is provisioned.
+1. Parameters that are not defined in the preset can still be customized by users when they claim a workspace.
+
+## Prerequisites
+
+- [**Premium license**](../../licensing/index.md)
+- **Compatible Terraform provider**: Use `coder/coder` Terraform provider `>= 2.4.0`.
+- **Feature flag**: Enable the `workspace-prebuilds` [experiment](../../../reference/cli/server.md#--experiments).
+
+## Enable prebuilt workspaces for template presets
+
+In your template, add a `prebuilds` block within a `coder_workspace_preset` definition to identify the number of prebuilt
+instances your Coder deployment should maintain:
+
+   ```hcl
+   data "coder_workspace_preset" "goland" {
+     name = "GoLand: Large"
+     parameters = {
+       jetbrains_ide = "GO"
+       cpus          = 8
+       memory        = 16
+     }
+     prebuilds {
+       instances = 3  # Number of prebuilt workspaces to maintain
+     }
+   }
+   ```
+
+After you publish a new template version, Coder will automatically provision and maintain prebuilt workspaces through an
+internal reconciliation loop (similar to Kubernetes) to ensure the defined `instances` count are running.
+
+## Prebuilt workspace lifecycle
+
+Prebuilt workspaces follow a specific lifecycle from creation through eligibility to claiming.
+
+1. After you configure a preset with prebuilds and publish the template, Coder provisions the prebuilt workspace(s).
+
+   1. Coder automatically creates the defined `instances` count of prebuilt workspaces.
+   1. Each new prebuilt workspace is initially owned by an unprivileged system pseudo-user named `prebuilds`.
+      - The `prebuilds` user belongs to the `Everyone` group (you can add it to additional groups if needed).
+   1. Each prebuilt workspace receives a randomly generated name for identification.
+   1. The workspace is provisioned like a regular workspace; only its ownership distinguishes it as a prebuilt workspace.
+
+1. Prebuilt workspaces start up and become eligible to be claimed by a developer.
+
+   Before a prebuilt workspace is available to users:
+
+   1. The workspace is provisioned.
+   1. The agent starts up and connects to coderd.
+   1. The agent starts its bootstrap procedures and completes its startup scripts.
+   1. The agent reports `ready` status.
+
+      After the agent reports `ready`, the prebuilt workspace considered eligible to be claimed.
+
+   Prebuilt workspaces that fail during provisioning are retried with a backoff to prevent transient failures.
+
+1. When a developer requests a new workspace, the claiming process occurs:
+
+   1. Developer selects a template and preset that has prebuilt workspaces configured.
+   1. If an eligible prebuilt workspace exists, ownership transfers from the `prebuilds` user to the requesting user.
+   1. The workspace name changes to the user's requested name.
+   1. `terraform apply` is executed using the new ownership details, which may affect the [`coder_workspace`](https://registry.terraform.io/providers/coder/coder/latest/docs/data-sources/workspace) and
+      [`coder_workspace_owner`](https://registry.terraform.io/providers/coder/coder/latest/docs/data-sources/workspace_owner)
+      datasources (see [Preventing resource replacement](#preventing-resource-replacement) for further considerations).
+
+   The developer doesn't see the claiming process — the workspace will just be ready faster than usual.
+
+You can view available prebuilt workspaces in the **Workspaces** view in the Coder dashboard:

+Prebuilt workspaces are not updated after they are provisioned.
+
+When a template's active version is updated:
+
+1. Prebuilt workspaces for old versions are automatically deleted.
+1. New prebuilt workspaces are created for the active template version.
+1. If dependencies change (e.g., an [AMI](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/AMIs.html) update) without a template version change:
+   - You may delete the existing prebuilt workspaces manually.
+   - Coder will automatically create new prebuilt workspaces with the updated dependencies.
+
+The system always maintains the desired number of prebuilt workspaces for the active template version.
+
+## Administration and troubleshooting
+
+### Managing resource quotas
+
+Prebuilt workspaces can be used in conjunction with [resource quotas](../../users/quotas.md).
+Because unclaimed prebuilt workspaces are owned by the `prebuilds` user, you can:
+
+1. Configure quotas for any group that includes this user.
+1. Set appropriate limits to balance prebuilt workspace availability with resource constraints.
+
+If a quota is exceeded, the prebuilt workspace will fail provisioning the same way other workspaces do.
+
+### Template configuration best practices
+
+#### Preventing resource replacement
+
+When a prebuilt workspace is claimed, another `terraform apply` run occurs with new values for the workspace owner and name.
+
+This can cause issues in the following scenario:
+
+1. The workspace is initially created with values from the `prebuilds` user and a random name.
+1. After claiming, various workspace properties change (ownership, name, and potentially other values), which Terraform sees as configuration drift.
+1. If these values are used in immutable fields, Terraform will destroy and recreate the resource, eliminating the benefit of prebuilds.
+
+For example, when these values are used in immutable fields like the AWS instance `user_data`, you'll see resource replacement during claiming:
+
+![Resource replacement notification](../../../images/admin/templates/extend-templates/prebuilt/replacement-notification.png)
+
+To prevent this, add a `lifecycle` block with `ignore_changes`:
+
+```hcl
+resource "docker_container" "workspace" {
+  lifecycle {
+    ignore_changes = all
+  }
+
+  count = data.coder_workspace.me.start_count
+  name  = "coder-${data.coder_workspace_owner.me.name}-${lower(data.coder_workspace.me.name)}"
+  ...
+}
+```
+
+For more targeted control, specify which attributes to ignore:
+
+```hcl
+resource "docker_container" "workspace" {
+  lifecycle {
+    ignore_changes = [name]
+  }
+
+  count = data.coder_workspace.me.start_count
+  name  = "coder-${data.coder_workspace_owner.me.name}-${lower(data.coder_workspace.me.name)}"
+  ...
+}
+```
+
+Learn more about `ignore_changes` in the [Terraform documentation](https://developer.hashicorp.com/terraform/language/meta-arguments/lifecycle#ignore_changes).
+
+_A note on "immutable" attributes: Terraform providers may specify `ForceNew` on their resources' attributes. Any change
+to these attributes require the replacement (destruction and recreation) of the managed resource instance, rather than an in-place update.
+For example, the [`ami`](https://registry.terraform.io/providers/hashicorp/aws/latest/docs/resources/instance#ami-1) attribute on the `aws_instance` resource
+has [`ForceNew`](https://github.com/hashicorp/terraform-provider-aws/blob/main/internal/service/ec2/ec2_instance.go#L75-L81) set,
+since the AMI cannot be changed in-place._
+
+### Current limitations
+
+The prebuilt workspaces feature has these current limitations:
+
+- **Organizations**
+
+  Prebuilt workspaces can only be used with the default organization.
+
+  [coder/internal#364](https://github.com/coder/internal/issues/364)
+
+- **Autoscaling**
+
+  Prebuilt workspaces remain running until claimed. There's no automated mechanism to reduce instances during off-hours.
+
+  [coder/internal#312](https://github.com/coder/internal/issues/312)
+
+### Monitoring and observability
+
+#### Available metrics
+
+Coder provides several metrics to monitor your prebuilt workspaces:
+
+- `coderd_prebuilt_workspaces_created_total` (counter): Total number of prebuilt workspaces created to meet the desired instance count.
+- `coderd_prebuilt_workspaces_failed_total` (counter): Total number of prebuilt workspaces that failed to build.
+- `coderd_prebuilt_workspaces_claimed_total` (counter): Total number of prebuilt workspaces claimed by users.
+- `coderd_prebuilt_workspaces_desired` (gauge): Target number of prebuilt workspaces that should be available.
+- `coderd_prebuilt_workspaces_running` (gauge): Current number of prebuilt workspaces in a `running` state.
+- `coderd_prebuilt_workspaces_eligible` (gauge): Current number of prebuilt workspaces eligible to be claimed.
+
+#### Logs
+
+Search for `coderd.prebuilds:` in your logs to track the reconciliation loop's behavior.
+
+These logs provide information about:
+
+1. Creation and deletion attempts for prebuilt workspaces.
+1. Backoff events after failed builds.
+1. Claiming operations.
