Manual PyPI run 43168818885 failed during checkout because forge-msgs-v2.0.1 did not exist; it never reached package upload. Selecting a tag name in Run workflow does not create one.

Prepare the requested Msgs 2.1.0 family release (forge-msgs-v2.1.0), synchronizing Python/Rust/C++ versions and the two locks. Keep Pillow >=13,<14, the v1 Arrow interface and other package-family versions unchanged. Check that release tags exist and are annotated before checkout, with regression coverage for missing/lightweight/valid tags. Update both README languages and correct the Trusted Publisher owner to PhyAgentOS in the release guide.

Validation:

• Python: 923 passed, including three executions of the actual resolver shell against tag API outcomes; Ruff/schema/version gate passed.
• Rust: 137 passed; both workspace crates packaged and verified.
• Msgs 2.1.0 wheel and sdist built and validated from a clean commit; SHA256SUMS generated.
• Actual candidate-wheel environment reports Msgs 2.1.0 / Pillow 13.0.0 / Dora 1.0.1. Standalone Gateway dora run (10s) and image/depth/state chain containing adapter-forge-gateway (10s) passed with exit 0 and HTTP/WebSocket assertions. This is a small synthetic smoke test, not hardware, sustained-run or the previously failing 640x480 multi-consumer acceptance.
• C++ validation is performed by the PR's Linux CI.

After CI and review, merge the fix and create an annotated forge-msgs-v2.1.0 tag at that exact merged release commit. No package upload or GitLab synchronization has happened as part of this PR.
