What's New in 0.1.8

🚀 Worker Pool V2: Dynamic Scaling

The bot now features an optional Worker Pool V2 with intelligent dynamic scaling:

Lazy Initialization: Starts with minimal workers (default: 1) and scales up as needed
Auto-Scaling: Automatically spawns workers when queue grows, up to configured max (default: 8)
Idle Scale-Down: Terminates idle workers after timeout (default: 15 min), keeping minimum workers alive
Configurable Limits: Full control via environment variables:
- WORKER_POOL_V2_ENABLED - Enable V2 (default: false)
- WORKER_POOL_MIN_WORKERS - Minimum workers to keep (default: 0)
- WORKER_POOL_MAX_WORKERS - Maximum workers allowed (default: 8)
- WORKER_POOL_INITIAL_WORKERS - Workers to spawn on startup (default: 1)
- WORKER_POOL_IDLE_TIMEOUT_MS - Idle timeout before scaling down (default: 15 min)
- WORKER_POOL_IDLE_CHECK_INTERVAL_MS - How often to check for idle workers (default: 5 min)

🛑 Graceful Shutdown Enhancement

New graceful drain option for Docker deployments:

Graceful Drain Mode: When enabled, the bot processes pending tasks before shutting down instead of immediately rejecting them
Configuration:
- GRACEFUL_DRAIN - Enable graceful drain (default: false for safety)
- GRACEFUL_DRAIN_TIMEOUT_MS - Max time to drain queue (default: 8000ms, max: 9500ms for Docker compatibility)
Docker Compatible: Default timeout fits within Docker's 10s grace period
Scales During Drain: When draining, pool temporarily spawns extra workers beyond normal limits to process queue faster

🧪 Testing Improvements

Added comprehensive WorkerPoolV2 test suite (9 tests)
Created Docker graceful shutdown test script (docker/test-graceful-shutdown.sh)
Updated shutdown integration tests
All 77 tests passing

📝 Documentation

Updated README with new environment variables
Added Docker deployment section with graceful shutdown documentation
Updated .env.example with all new configuration options

🔧 Other Improvements

Added correlation ID support for operation tracing in logs
Restructured project with src/ directory for better organization
Improved graceful shutdown handler with timeout and healthcheck cleanup
Updated dependencies (grammy 1.39.3 → 1.40.0)

🐛 Bug Fixes

Fixed worker path resolution in hellspawn.ts
Fixed CI test paths after directory restructure
Fixed Dependabot target branch configuration

🏗️ Infrastructure

Removed lockfile from repository
Updated Docker build tags (removed commit hash tags)
Updated Bun version in CI to 1.3.9

📋 Breaking Changes

None. All changes are backward compatible. Worker Pool V2 is opt-in via WORKER_POOL_V2_ENABLED=false (default).
