## What's new

- Tests for PUSHB deduplication (same-batch and cross-batch)
- Tests for CLI server argument re-injection (`--host`, `-p`, `--host=VALUE`, `--port=VALUE`)
- Test for ping response structure validation
- E2E TCP deduplication test script (`scripts/tcp/test-dedup-tcp.ts`)

## Bugfixes

- **TCP deduplication**: `jobId` deduplication now works correctly in TCP mode. The auto-batcher was sending `jobId` instead of `customId` in PUSHB commands, causing the server to skip deduplication for all batched operations ([#10](https://github.com/egeominotti/bunqueue/issues/10))
- **CLI `--host` and `-p` flags**: `bunqueue start --host 127.0.0.1 -p 6666` now correctly binds to the specified host and port. Previously, `parseGlobalOptions()` consumed these flags as global options, removing them before the server could use them ([#9](https://github.com/egeominotti/bunqueue/issues/9))
- **Docker healthcheck**: Changed healthcheck URL from `localhost` to `127.0.0.1` to avoid IPv6 resolution issues in Alpine containers ([#7](https://github.com/egeominotti/bunqueue/issues/7))
- **TCP ping health check**: Fixed ping response parsing from `response.pong` to `response.data.pong` matching the actual server response structure ([#5](https://github.com/egeominotti/bunqueue/issues/5))

## Documentation

- Updated deployment guide healthcheck example (`localhost` → `127.0.0.1`)
- Clarified that `jobId` deduplication works in both embedded and TCP modes
- Added `--host` flag example to CLI start command reference
