chore: bump TechEngine submodule to ff4e11e

This brings in GetTechAPI/TechEngine#134, the engine's own cleanup. The
engine no longer carries TechAPI as a submodule, so the two repos stop
pointing at each other. app/dump_check.py, app/verify/baseline.py and
passmark_ids.json are gone; nothing here called them. integrity_check.py
now reads the directory app.data_root resolves when no path is given,
instead of a Windows path that existed on one machine.

collect.yml's three `uses:` move to the same commit. In the reusable
workflows only a comment changed; the collectors, the validator and the
dump code are untouched.
