v0.4.0

What's New

Major architecture improvements - DB-backed config store, mandatory LLM gateway, and simplified deployment (removed load balancer).

Breaking Changes

• LLM Gateway is now mandatory (merged proxy into gateway)
• Load balancer removed - Tower exposed directly on TOWER_PORT
• ICC enabled on worker network (workers can reach gateway)

New Features

• Config Store - profiles, engines, and templates stored in PostgreSQL with in-memory cache
• Config UI - manage configs from the dashboard with export JSON button
• Gateway OAuth - support for OAuth token (Pro/Max subscription)
• Full CRUD API for configs (/configs/{type}/{name})

Improvements

• Split tower into store/ and runner/ sub-packages
• Extracted Prometheus metrics into dedicated module
• Hardened runner logic (sanitization, output collection, recovery)

Internal

• 19 new unit tests (config store, pool, job runner, worker)
• Updated all documentation to match current architecture
