chore(lint): bump golangci-lint to v2.11.1 (#7905)

- Added nolint to plugin/auto/walk.go to avoid a symlink/TOCTOU
  warning, as it needs to follow symlink.
- Replaced a few flagged integer conversions with safe equivalents in
  cache hashing, reuseport socket setup, and TLS arg handling
- Preallocated response rule slices in plugin/rewrite/name.go
- Replaced WriteString(fmt.Sprintf/Sprintln(...)) with direct
  fmt.Fprint* calls
- Removed stale nolint directives from code and tests that are no
  longer needed
