Fix Chrome extension release recovery and API upload

[Juice10]

Summary

• migrate Chrome Web Store publishing from the deprecated API v1 action to pinned chrome-webstore-upload-cli@4.0.1 using API v2
• preserve automatic stable and next extension publishing after successful npm releases
• document dashboard-based manual recovery without broadening the privileged npm release workflow
• correct stale master references in the release-channel documentation

Required repository setup

Production publishing uses CWS_PUBLISHER_ID; the next channel uses NEXT_CWS_PUBLISHER_ID alongside its existing NEXT_CWS_* credentials.

Validation

• focused workflow and documentation assertions pass
• workflow YAML, Prettier, actionlint, and git diff --check pass
• the extension prepublish build succeeds
• chrome.zip passes integrity validation and contains Manifest V3 version 2.1.1

The full local monorepo baseline has unrelated Puppeteer target-close/time-out failures and a missing generated rrvideo/build/cli.js; the PR's GitHub checks are the remote integration gate.

Pull request overview

This PR adds a manual (workflow_dispatch) recovery path to the release workflow so Chrome extension build/upload steps can be triggered even when the npm publication path didn’t mark a release as “published”.

Changes:

• Adds a workflow_dispatch boolean input (publish_chrome_extension) to manually trigger Chrome extension publishing.
• Extends the existing Chrome extension build/upload if: conditions to also run when manually requested.
• Keeps the existing automatic behavior that runs extension publishing after a successful Changesets npm publish.
