* 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)
