Greptile Summary

Automated Release Please PR bumping the workspace from 0.4.1 to 0.4.2, covering two bug fixes (docker proxy log redaction, RPC EOF detection), several agent/vmnet module extraction refactors, an integration test suite for arcbox-vmnet, and a dependency bump for dimicon. The three changed files are the standard Release Please artifacts: the manifest, changelog, and root Cargo.toml.

Confidence Score: 5/5

Safe to merge — purely automated release bookkeeping with no logic changes.

All three changed files are standard Release Please artifacts (manifest, changelog, Cargo.toml version strings). No logic, API surface, or runtime behaviour is altered. The only notable observation is a cosmetic version-history gap for arcbox-hv, which is a P2 style note and does not affect the build or correctness.

No files require special attention.

Important Files Changed

Filename	Overview
.release-please-manifest.json	Version manifest bumped from 0.4.1 to 0.4.2 by Release Please automation.
