Port TEA commands into workflows and preload Murat knowledge (#660)

* Port TEA commands into workflows and preload Murat knowledge

* Broke the giant knowledge dump into curated fragments under src/modules/bmm/testarch/knowledge/

* Broke the giant knowledge dump into curated fragments under src/modules/bmm/testarch/knowledge/

* updated the web bunles for tea, and spot updates for analyst and sm

* Replaced the old TEA brief with an indexed knowledge system: the agent now loads topic-specific
  docs from knowledge/ via tea-index.csv, workflows reference those fragments, and risk/level/
  priority guidance lives in the new fragment files

+# Fixture Architecture Playbook
+
+- Build helpers as pure functions first, then expose them via Playwright `extend` or Cypress commands so logic stays testable in isolation.
+- Compose capabilities with `mergeTests` (Playwright) or layered Cypress commands instead of inheritance; each fixture should solve one concern (auth, api, logs, network).
+- Keep HTTP helpers framework agnostic—accept all required params explicitly and return results so unit tests and runtime fixtures can share them.
+- Export fixtures through package subpaths (`"./api-request"`, `"./api-request/fixtures"`) to make reuse trivial across suites and projects.
+- Treat fixture files as infrastructure: document dependencies, enforce deterministic timeouts, and ban hidden retries that mask flakiness.
