Changes:
1. openStore() now async, auto-creates directory and bootstraps
2. Removed shouldCreate parameter and validateStoreExists()
3. All openStore() calls now awaited
4. Deleted init and bootstrap commands
5. Removed Issue #55 store validation tests (superseded by auto-bootstrap)
6. Enhanced error handling in openStore() for permission/path issues
7. Updated e2e snapshots after fixing missed await in cmdRender
Bootstrap is idempotent. Core tests using createMemoryStore() unaffected.
Fixes#73
