Crystal worker — polls MySQL for PENDING runs, claims one atomically, executes
the estimation engine, streams progress into the run row, writes outputs.

No web framework. MySQL is the only interface between the PHP dashboard and
this process. Run under systemd (see crystal-worker.service).

Engine integration point: run_estimation() below. Today it calls the demo
engine (engine_stub) so the full loop works end to end; Steps 0-7 of the
rebuild replace that one import with the real engine package.

    Replace `engine_stub` with the real engine package as the rebuild lands:
        from crystal_engine import run_pipeline
        result = run_pipeline(upload, exports_dir=EXPORTS,
                              on_progress=lambda p, s, d: progress(...))
    The contract stays identical: read the upload, call progress() as stages
    advance, write summary/detailed workbooks + <run>_flags.json to EXPORTS,
    then call finish().
