feat(m6c): add Linux release package and delivery docs

[Change Nature]
- This commit adds the M6c Linux delivery surface without changing simulation behavior.

[New Capability]
- Publish self-contained linux-x64 output with framework-dependent fallback and a package-relative launcher.
- Document the menu, controls, save paths, autoplay verification, milestones, and asset/license boundaries.

[Implementation]
- Add the M6c packaging and startup scripts.
- Add release notes and an asset/license inventory.
- Keep release artifacts and verification evidence under ignored artifacts/m6c-release/.

[Impact]
- Runtime code and M3 acceptance artifacts are unchanged.
- The package was exercised under Xvfb; prior provider metadata remains an unstaged worktree change.
