chore(lint): ignore .claude/** worktrees and align check-user mock with RateLimitResult

Two small follow-ups to the v1.4.41 inline-QA reconcile:

- eslint.config.mjs gains `.claude/**` in the globalIgnores list so a
  mid-marathon Claude Code worktree on an older base commit can no
  longer poison `pnpm lint` locally with pre-fix warnings. CI never
  walks that path; the change is purely for the dev environment.

- The check-user route test mock objects for `checkRateLimit` carried
  a stray `limit: 30` field that does not exist on `RateLimitResult`
  (the real type is `{ allowed, remaining, resetAt }`). The literal
  was harmless at runtime but flagged by `tsc --noEmit` on the
  test-file declarations. Drops the field at all three mock sites.
