* feat: set qwen3.5:latest as default model
- Make qwen3.5:latest the primary default model for faster inference
- Move llama3.1:8b-instruct to fallback chain
- Update text fallback chain to prioritize qwen3.5:latest
Retains full backward compatibility via cascade fallback.
* test: remove ~55 brittle, duplicate, and useless tests
Audit of all 100 test files identified tests that provided no real
regression protection. Removed:
- 4 files deleted entirely: test_setup_script (always skipped),
test_csrf_bypass (tautological assertions), test_input_validation
(accepts 200-500 status codes), test_security_regression (fragile
source-pattern checks redundant with rendering tests)
- Duplicate test classes (TestToolTracking, TestCalculatorExtended)
- Mock-only tests that just verify mock wiring, not behavior
- Structurally broken tests (TestCreateToolFunctions patches after import)
- Empty/pass-body tests and meaningless assertions (len > 20)
- Flaky subprocess tests (aider tool calling real binary)
All 1328 remaining tests pass. Net: -699 lines, zero coverage loss.

* fix: prevent test pollution from autoresearch_enabled mutation
test_autoresearch_perplexity.py was setting settings.autoresearch_enabled = True
but never restoring it in the finally block — polluting subsequent tests.
When pytest-randomly ordered it before test_experiments_page_shows_disabled_when_off,
the victim test saw enabled=True and failed to find "Disabled" in the page.
Fix both sides:
- Restore autoresearch_enabled in the finally block (root cause)
- Mock settings explicitly in the victim test (defense in depth)

* 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
