Remove blocking logic that prevented writes to files outside the
session directory. The guard now only applies to files within the
session directory, allowing free writes to external paths.
- Remove OUTSIDE_SESSION_MESSAGE constant
- Update test to expect outside writes to be allowed
- Add early return for paths outside session directory
- Keep isPathInsideDirectory for session boundary check
TDD cycle:
1. RED: Update test expectation
2. GREEN: Implement early return for outside paths
3. REFACTOR: Clean up unused constants
Forward session.deleted events to write-existing-file-guard so per-session read permissions are actually cleared in runtime.
Add plugin-level regression test to ensure event forwarding remains wired, alongside the expanded guard behavior and unit coverage.
