feat: log application path and table init during startup (#1109)

* feat: log application path and table init during startup

Adds info-level log lines so users know their app directory was found and
each GraphQL-schema table was initialised, filling the confidence gap when
running `harper dev /path/to/app`.

* fix: add worker-0 guard and optional chaining to startup logs

- Wrap app-path log in getWorkerIndex() === 0 to avoid duplicate lines
  from worker threads
- Use harperLogger.info?.() optional chaining per Harper conventions
- Add ?. to properties.find() for robustness

* fix: remove accidentally committed cache file, ignore cache/ dir

cache/projects.json is a Claude Code internal file containing a
machine-local path. Add cache/ to .gitignore to prevent recurrence.
