Process

Detect framework from project files (if not provided):
- spec/ + _spec.rb + .rspec = RSpec
- test/ + _test.rb = Minitest
- jest.config.js or *.test.js = Jest/Vitest
- go.mod + _test.go = Go test
- pytest.ini or conftest.py = pytest
Run tests (scoped if provided, otherwise full suite)
Parse output for pass/fail counts and failure details
