chore: add manually gated store publishing workflow

[dkrizan]

What

Adds .github/workflows/publish-stores.yml, which submits an already-built release to the Chrome Web Store and addons.mozilla.org, so releases no longer have to be uploaded to both stores by hand.

When it runs

Never automatically on a merge. Two triggers only:

• release: released — prerelease.yml already creates every release with prerelease: true. Unticking "pre-release" on the GitHub release fires this. That's the publish button.
• workflow_dispatch — takes a tag plus a both / chrome / firefox picker, for retries and per-store reruns.

Chrome and Firefox are separate jobs, so one store failing or rejecting doesn't block the other and only the broken one needs re-running.

How

The zips are downloaded from the release assets rather than rebuilt, so what ships is exactly what was tested and attached to the release.

AMO rejects bundler output without readable sources, so the Firefox job also submits git archive of the tagged tree via --upload-source-code. --approval-timeout 0 keeps the job from blocking on review. A web-ext lint step runs before submission to catch AMO validation errors before a review cycle is spent.

Verified

• Ran the download → unzip → lint chain against the real v1.9.0 release assets: globs match, the zip unpacks with manifest.json at top level so --source-dir is valid, and web-ext lint reports 0 errors / 5 warnings.
• Built locally and confirmed browser_specific_settings.gecko.id survives the crxjs build, so AMO matches the existing listing.
• git archive HEAD produces a clean 51-file source zip with no node_modules or dist-*.
• CLI flags checked against each tool's --help.

Required secrets

All six are already set on the repo: CHROME_EXTENSION_ID, CHROME_CLIENT_ID, CHROME_CLIENT_SECRET, CHROME_REFRESH_TOKEN, AMO_JWT_ISSUER, AMO_JWT_SECRET.

The Google Cloud OAuth consent screen is set to In production — while it sits in Testing, Google expires refresh tokens after 7 days and the Chrome job would start failing a week after setup.

Note on testing

workflow_dispatch only appears once the workflow is on the default branch, so this has to merge before it can be exercised. Merging is inert on its own — the workflow submits nothing without a release promotion or a manual dispatch.

One-time follow-up on the AMO side: the listing needs build instructions (Node 20, npm ci, NODE_ENV=production npm run build, output in dist-firefox/) so a reviewer can reproduce the bundle from the submitted sources.

Walkthrough

The pull request adds a GitHub Actions workflow for Chrome Web Store and Firefox Add-ons publication. It supports release and manual triggers, store selection, artifact downloads, authentication, Firefox linting, and source packaging. The README documents local extension builds and generated artifacts.

Changes

Extension store publishing

Layer / File(s)	Summary
Workflow orchestration and store publication .github/workflows/publish-stores.yml	The workflow supports release and manual triggers, concurrency control, store selection, release artifact downloads, Chrome publication, Firefox AMO linting, and Firefox submission.
Source build documentation README.md	The README documents supported systems, Node.js 20.x, build commands, output artifacts, Vite configurations, and manifest-based version reproducibility.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🟡 Moderate · up to b5afd

The workflow can run mutable, unpinned publishing dependencies with store credentials, so an upstream dependency change could alter release behavior or compromise store publishing. Pinning and reviewing the exact versions is needed before this is merge-ready.

Poem

I’m a rabbit in the build-room bright,
Bundles hop to stores tonight.
Chrome and Firefox clear the gate,
Lint and tags confirm their state.
Source notes rest in README light.

In @.github/workflows/publish-stores.yml:
- Line 59: Pin the publishing tools to exact reviewed versions in package.json
and package-lock.json, run npm ci before publishing, and invoke the installed
local binaries instead of npx or the mutable web-ext@latest reference. Update
the commands at .github/workflows/publish-stores.yml lines 59-59, 90-90, and
102-102; ensure the Chrome job checks out the repository before npm ci and uses
the lockfile.

In `@README.md`:
- Around line 69-71: Revise the README release-build statement to avoid claiming
byte-identical archive reproduction; state only that building the release tag
reproduces the release version and configuration, unless the documented
toolchain pinning and archive validation are added.
- Around line 51-60: Update the Build command in the README to use npm run build
without the Unix-specific NODE_ENV=production prefix, since the build script
does not require that environment variable.
