Added multiple layers of protection against circular redirects:
1. ResolveBeadsDir now detects when a redirect points back to itself
and auto-removes the errant redirect file with a warning
2. ensureBeadsRedirect now includes safety checks:
- Prevents creating redirects inside mayor/rig/ (the canonical location)
- Validates that the redirect target is not the same as the beads dir
3. Added test case for circular redirect detection
