docs(release): name the shipped computer-use 0.12.1 bundle

Record the actual embedded manifest version and canonical source revision
in the current release notes; regenerate the packaged TUI changelog.

Validation: bundled-plugin claim check passed; version state and 38 feature
references passed. npm test: 1286 passed, 0 failed, 7 skipped (web 767/767).
npm run check:web: lint, typecheck and production build passed.

The previous hosted Version drift failure was a missing version receipt,
not permission to waive the gate. Fresh exact-head CI remains required.
