__NAME__ — one-line description of what this workflow checks.

Python-profile scaffold: run PATH-checks `python3` (exit 2 if missing)
and then byte-compiles every .py file via `python3 -m compileall -q .`
as an inert default. Replace the compileall call with the actual check
this workflow needs. It executes with the repository root as the working
directory and the EECO_* variables in the environment.

Exit codes: 0 clean, 1 finding, 2 blocked (a required tool is missing),
3 AI pass deferred (no --ai).
