Editing a recipe's script does not invalidate outputs (code_version ignores script contents)

[lhparker1]

What happened

code_version is computed from the recipe command string + container image + decisions, but NOT from the contents of the script the command invokes. After materializing an output, editing the underlying script (e.g. changing the weighting logic in run_reconstruction.py) leaves lc status reporting the output as ok, and a plain lc run skips it as already-built. The output silently reflects stale code. The only ways to rebuild are lc run -f or deleting the output dir — both require the user to know the script changed, which defeats the point of provenance/staleness tracking.

Reproduction

1. lc run <output_id> to materialize an output whose recipe is python scripts/foo.py ....
2. Edit scripts/foo.py (change behavior, not the recipe command).
3. lc status -> still ok; lc run <output_id> -> skipped (no rerun).

Expected: a script-content change invalidates dependent outputs (hash the resolved script file(s), or the command's file dependencies, into code_version / a rerun-trigger).
