Restore #196, #202, #203 and the macOS release-runner change, reverted by the i18n chain (#229)

* Release CI: macOS job on macos-15-xlarge

Custom macOS larger runners in a runner group do not pick up jobs; the
built-in M2 Pro label does. Only release.yml uses it, and the
actions_macos_xl budget caps the monthly spend.

(cherry picked from commit 90d60b0c98)

* CI: tell actionlint about the org's macos-release runner label (#202)

Co-authored-by: Claude Opus 5.5 <noreply@anthropic.com>
(cherry picked from commit ddea3c72e0)

* About: contributor and model credits compiled in (grab bag + table, self-submitted names) (#196)

* About: contributors compiled in from contributors.json (grab bag + table, sortable, name toggle)

Adds About ▸ Contributors and About ▸ Models tabs per the craftrules standard
(standards/contributors.md): contributors/contributors.json is generated by
craftrules/scripts/contributors.py and baked into the binary by crates/ui-egui/build.rs as
static tables; nothing is read at run time. Each contributor line: @username, opt-in
display/real name, PRs, commits, lines +/−/Δ, binary assets +/−, first/last commit.
Sortable by every column; alphabetical ignores case and the leading @.

* Contributors: self-submitted names in contributors/people.toml; AGENTS.md credit-yourself section

build.rs reads contributors/people.toml next to the generated contributors.json and shows a name only
for entries the generator verified as written by that person (craftrules standards/contributors.md).
