test(dolt): add concurrent writer tests for embedded Dolt
Validates Gas Town multi-polecat concurrent access scenarios:
- Concurrent issue creation (10 goroutines)
- Same-issue update race conditions
- Read-write mix (5 readers, 5 writers, 100 iterations)
- Long transaction blocking
- Branch-per-agent merge race
- Worktree export isolation
- Concurrent dependency operations
- High contention stress test (20 workers, 1000 ops)
Also fixes Status() to scan string status from dolt_status table.
All tests pass with 100% success rate under contention.
