Alexander Whitestone b615595100 refactor: centralize config & harden security (#141)
* feat: upgrade primary model from llama3.1:8b to qwen2.5:14b

- Swap OLLAMA_MODEL_PRIMARY to qwen2.5:14b for better reasoning
- llama3.1:8b-instruct becomes fallback
- Update .env default and README quick start
- Fix hardcoded model assertions in tests

qwen2.5:14b provides significantly better multi-step reasoning
and tool calling reliability while still running locally on
modest hardware. The 8B model remains as automatic fallback.

* security: centralize config, harden uploads, fix silent exceptions

- Add 9 pydantic Settings fields (skip_embeddings, disable_csrf,
  rqlite_url, brain_source, brain_db_path, csrf_cookie_secure,
  chat_api_max_body_bytes, timmy_test_mode) to centralize env-var access
- Migrate 8 os.environ.get() calls across 5 source files to use
  `from config import settings` per project convention
- Add path traversal defense-in-depth to file upload endpoint
- Add 1MB request body size limit to chat API
- Make CSRF cookie secure flag configurable via settings
- Replace 2 silent `except: pass` blocks with debug logging in session.py
- Remove unused `import os` from brain/memory.py and csrf.py
- Update 5 CSRF test fixtures to patch settings instead of os.environ
