refactor(quick-capture): replace intent router with native tool-calling

Removes the custom classify_capture_intent + _process_note two-pass
approach. The LLM now picks the right tool directly via Ollama's native
tool_calls API (same path as the main chat pipeline). _should_think
decides whether extended reasoning is needed based on input length/
complexity. intent.py deleted — no longer needed.

Android app and response format unchanged.
