chat-rag-explorer: v0.5.0

0.5.0 (2026-08-01)

⚠ BREAKING CHANGES

• OPENROUTER_API_KEY, OLLAMA_API_KEY, OPENROUTER_BASE_URL and OLLAMA_BASE_URL are no longer read. Rename them to LLM_API_KEY and LLM_BASE_URL; startup names the replacement for any that remain.
• LLM_PROVIDER is now required. An existing .env without it will start but fail API calls until LLM_PROVIDER=openrouter (or ollama) is added. .env.example ships it in the REQUIRED section.

Features

• collapse per-provider connection settings into LLM_API_KEY/LLM_BASE_URL (ba194ca)
• require LLM_PROVIDER instead of defaulting to openrouter (7db83c9)

Bug Fixes

• run renamed-settings check before the missing-.env early return (d956cd2)

Documentation

• restructure provider setup around the unified LLM_* settings (a2e3ca8)
