## Summary
This PR implements Spec 206 end to end and establishes the first checked-in test suite governance foundation for the platform app.
Key changes:
- add manifest-backed test lanes for fast-feedback, confidence, browser, heavy-governance, profiling, and junit
- add budget and report helpers plus app-local artifact generation under `apps/platform/storage/logs/test-lanes`
- add repo-root Sail-friendly lane/report wrappers
- switch the default contributor test path to the fast-feedback lane
- introduce explicit fixture profiles and cheaper defaults for shared tenant/provider test setup
- add minimal/heavy factory states for tenant and provider connection setup
- migrate the first high-usage and provider-sensitive tests to explicit fixture profiles
- document budgets, taxonomy rules, DB reset guidance, and the full Spec 206 plan/contracts/tasks set
