refactor(cli): simplify updater, remove cache and confirmation

- Remove the 24h disk cache (State, readState/writeState, checkInterval)
  that served stale latest versions within the TTL window
- Remove file lock (Flock) and confirmation prompt (Prompt/Terminal)
- Every check now hits the npm registry directly
- Updates always auto-install on any version mismatch within the same
  major, including rollbacks where the registry version is lower
- Drop the interactive option from check() and the confirm/declined/
  dismissed action concepts
