fix(opencode): Mac review of the Linux fixes - a clean db has no sidecars on Mac either, the placeholder needs its example, a home install must run, status and reconcile read the db read-only (Issue #60, PR #62)

- tests: macOS SQLite keeps -wal/-shm after the last close (persistent WAL);
  the `clean` state removes them after the checkpointing close
- the 2.x placeholder pattern requires the quoted example, so a typed
  `Ask anything…` is read as a draft
- auth_ok takes ~/.opencode/bin/opencode only as an executable file
- status.sh and reconcile.sh (drift C) open opencode.db with _ro_connect
