chore: upgrade nostr-* packages to rev 4767ad13

- Update nostr-relay-builder, nostr-sdk, nostr-lmdb to latest revision
- Update grasp-audit nostr-sdk dependency
- Fix clippy warnings:
  - Replace .clone() with std::slice::from_ref() in src/git/sync.rs
  - Change &PathBuf to &Path in tests/common/git_server.rs
  - Replace vec![] with array literal in src/purgatory/sync/functions.rs
- Update PR_TEST_COMMIT_HASH in grasp-audit due to event generation changes

All 249 tests passing, no breaking changes required.
