Jake WriterandClaude Opus 5.5 11969fa44a Prerelease on every tested merge, promote by tag, and pair each library release with its browser (#810)
* Pair each library release with the browser build it was tested with

Nothing tied a library release to a browser build: `camoufox fetch` took the
newest build in a channel, and a launch used whatever config.json marked
active, so an upgraded library could run a browser it was never tested with,
and an old library would pick up a newer, incompatible browser.

A released package now carries browser-pin.json, naming the browser release
built from the same sources. With it, and no explicit choice by the user:

- fetch installs exactly that build (no prerelease prompt: it is the build
  this release was tested with, prerelease or not);
- a launch uses exactly that build, whatever else is installed or active,
  and reports it as not installed rather than falling back to another;
- the fetcher's automatic install (TypeScript's first run) takes only it.

An explicit `camoufox set` still wins, with a one-time warning at launch;
`camoufox set --release` returns to the paired build, and `camoufox active`
says which is in use. The checked-in pin is `{}`, so development checkouts
follow their channel as before.

Also: prerelease library versions (0.5.8b1, 0.5.8-beta.1) parse as their
release; they were read as 0.5.0.

* Release a prerelease on every tested merge; promote to stable by tag

Every merge to main whose tests pass now publishes a prerelease of all
three artifacts, and pushing vX.Y.Z on a tested main commit promotes it.

- Build and Release runs after Tests on main. It builds the browser only
  when its sources changed (ci.browser_inputs.source_digest: every browser
  input, not counting the release number). Each build gets the next unused
  beta.N on a release commit beside main -- main is protected -- and is
  published as a GitHub prerelease, not a draft, with its source digest in
  the notes.
- Publish to pypi follows it: <next>bN on PyPI, then Publish to npm puts
  <next>-beta.N under the `next` dist-tag. Both are stamped with the browser
  release built from the same sources.
- A vX.Y.Z tag is refused unless the commit is on main and `All tests
  passed` succeeded on it. The paired browser prerelease then becomes the
  stable, latest release (no rebuild, so users get the tested binaries), and
  X.Y.Z goes to PyPI and npm `latest`.

The tested commit travels between workflows as an artifact: a workflow_run
is told main's head, so two quick merges would otherwise publish the second,
untested one. ci/release.py holds the planning, stamping and promotion,
unit-tested in ci/tests/test_release.py.

Also fixes two checks that failed the manual release already: vermin
targeted Python 3.8 exactly, against a package that declares ^3.10 and a
code base that needs 3.9, and check-pack compared npm and PyPI prerelease
versions as strings, although each registry spells them differently.

* Test driver-only pull requests against the release paired with their sources

The scope step matched the release tag named by upstream.sh. With release
numbers now allocated per build, that number is a floor, not a release, so
driver-only pull requests would nearly always rebuild, or fetch a build other
than the one their sources produce. It now asks `ci.release paired` for the
release built from exactly this tree's browser sources, and fetch-browser
installs it through the same pin a released package carries.

Documents the release flow in ci/README.md.

* pythonlib: replace asyncio.to_thread so the 3.8 vermin gate passes

publish-pypi.yml checks the package with
`vermin . --eval-annotations --target=3.8 --violations camoufox/`, and
asyncio.to_thread (Python 3.9+) in _resolve_proxy_geo failed it, stopping
the 0.5.7 release. loop.run_in_executor does the same off-loop lookup.

* Pair with releases cut before the digest marker, and test the pairing against the step

The scope step now asks ci.release paired, which only knew releases whose notes
carry a source digest. None does yet: v156.0.1-beta.32, the release built from
main's sources, predates the marker. So every driver-only pull request would have
rebuilt the browser, the first merge would have cut a duplicate beta.33, and the
two scope tests in ci/tests/test_ci.py -- which ran the step in a scratch repo
where ci.release did not import -- failed.

find_paired falls back to the tag upstream.sh names when that release is
published (a prerelease counts; a draft does not) and no browser source changed
since, listing the files that did when they have. browser-plan and promote use
the same lookup. paired takes --root and --releases so the tests run the
workflow's own step against a scratch repo and a fixed release list.

* Release from one workflow, with trusted publishing

The release chain was four workflows linked by workflow_run, with the
tested commit carried between them as an artifact; a browser release
number committed beside main; pairing data in HTML comments in release
notes; a stored PyPI token; and packages rebuilt at each publish.

release.yml now does all of it with `needs`:

- On a push to main it calls tests.yml on the pushed commit (tests.yml
  loses its own push trigger), then builds the browser only when its
  sources changed, and publishes a library prerelease only when something
  a package ships changed. Docs- and CI-only merges publish nothing.
- A browser release's number lives only in its tag, which points at the
  tested main commit; `ci.release set-build` writes it into the build's
  working tree. Nothing is committed.
- Each browser release carries a manifest.json asset (source digest,
  commit), which is what a library pairs by. Builds are attested with
  actions/attest-build-provenance.
- Both packages are built once, in build-library, and the publish jobs
  upload exactly those files. PyPI and npm use trusted publishing; no
  credential is stored.
- A vX.Y.Z tag builds and checks both packages before promoting the
  paired browser and publishing.
- Every published library version is tagged (vX.Y.ZbN for a prerelease),
  which is how the next merge tells whether the library changed.
- A failed publish is retried with "Re-run failed jobs"; the retry-only
  workflow_dispatch path is gone.
