This PR fixes the issue where console monitoring was empty when a specific shard was targeted on the official Screeps server.
### Changes:
- **Unified Subscription**: Changed WebSocket subscription path from `shard/console` (invalid) to the global `console` channel.
- **Shard Filtering**: Implemented client-side filtering in `handleConsoleEvent` to only display logs matching the targeted shard.
- **Precise Timing**: Retained the shard-specific `api.time()` call for accurate tick duration tracking.
- **Tests**: Added and updated 48 unit tests verifying the fix and shard filtering logic.
- **Distribution**: Rebuilt `dist/index.js` and bumped version to `v0.2.1`.
