## Changes
- **Commit 1**: Remove 17 unnecessary `//nolint` directives:
- `//nolint:varnamelen` — linter not active
- `//nolint:unused` on exported `SlimUnsupported`
- `//nolint:govet` in `coderd/httpmw/csrf` — no longer fires
- `//nolint:revive` on functions refactored since the nolint was added
- `//nolint:paralleltest` citing Go 1.22 loop variable capture
(obsolete)
- Bare `//nolint` narrowed to specific `//nolint:gocritic` with
justification
- **Commit 2**: Fix root causes behind 5 dangerous nolint suppressions:
- Add `MinVersion: tls.VersionTLS12` to TLS client config (removes
`gosec` G402)
- Delete trivial unexported wrappers `apiKey()`/`normalizeProvider()` in
chatprovider (removes `revive` confusing-naming)
- Add doc comments to `StartWithAssert` and `Router` (removes `revive`
exported)
- Rename unused parameters to `_` in integration test helpers
