Address Copilot review; move release process into the make-release skill

- README: restore the separate CH32V103 / CH583,CH582 rows in the Supported
  CPUs table — the merged row wrongly applied "ISO data loss [2]" to CH583/2
- Fix typos in historical changelog entries (santiy, Venndor, dynamnic, bagde,
  masstorage, techinical, walkaround, "Update Update") flagged by Copilot
- Replace the AGENTS.md Release section with a pointer to the make-release
  skill; add a Finalize step (maintainer commit/tag/push + GitHub release) to
  the skill so nothing is lost

 Confirm version is consistent across `tusb_option.h` / `library.json` / `repository.yml` / `sonar-project.properties`, then leave everything unstaged for the maintainer.
