Steve Yegge f987722f96 Code review fixes for cache eviction (bd-145)

Oracle-recommended improvements:

**Thread Safety:**
- Fix lastAccess race: updates now under Write lock
- Make Stop() idempotent with sync.Once
- Close stores synchronously (not in goroutine)

**Performance:**
- Replace O(n²) sort with sort.Slice (O(n log n))
- Enforce LRU immediately on insert (prevents FD spikes)

**Correctness:**
- Canonicalize cache key to repo root (not cwd)
  - Prevents duplicate connections for same repo
  - Multiple subdirs → single cache entry
- Validate env vars: TTL <= 0 falls back to default

**Tests (6 new edge cases):**
- Canonical key behavior across subdirectories
- Immediate LRU enforcement without periodic cleanup
- Invalid TTL handling
- Re-open after eviction
- Stop idempotency
- All tests pass with -race flag

This addresses potential data races, resource spikes, and duplicate
connections identified during code review.
