fix(release): stable Linux source-scope probe receipt

[leoisadev1]

Summary

• Build release linux 37621664130 (@ e37711c / fix(release): stable LLVM source digest #66) passed AppImage/deb/rpm/linux tar.gz on both rebuilds, then failed compare on convt-0.2.0-source.tar.gz.
• Sole differing member: third-party/linux-source-scope/remove-sdk-only-probe.json (same mtime/mode; content hash drift). Manifests failed because they embed the source archive hash.
• Cause: probe receipt stored full cargo stderr after $SOURCE / $EMPTY_CARGO_HOME substitution. Parallel cargo output still drifts across rebuilds.
• Fix: keep deterministic fields only (command, empty_cargo_home, exit_code).

Test plan

• python3 -m py_compile scripts/release/linux-source-scope.py
• Re-dispatch Build release linux for v0.2.0; expect dual-build compare green and linux-release-review artifact
• Upload AppImage/deb/rpm/linux tar.gz to release v0.2.0 (keep Mac/Win)

[Low risk] Adjusts release build probe logging.

This PR appears safe to merge; it removes variable receipt content without changing release checks.

What we checked:

• Source checks remain in place: No. The script still rejects blocked SDK packages in the build graph, changed build graphs, and changed retained source files.

Summary

Removes Cargo stderr from remove-sdk-only-probe.json so changing output order and temporary paths no longer change the Linux source archive.

• Keeps command, empty_cargo_home, and exit_code.
• Leaves the probe and existing source checks unchanged.
• No actionable issues found. The dual-build release comparison was not run during this review.
• Reduced diagnostic detail is intentional: leoisadev1 explicitly described keeping only deterministic fields in the PR description.
