#373 fix(runtime): check out repo in publish jobs (exit 127 — publish never ran)

Hotfix for the auto-publish regression from [#372]

[#372] extracted the channel-publish logic into scripts/publish-runtime-channel.sh, but the publish-staging / publish-production jobs in build-mlx-runtime.yml never run actions/checkout, so the script isn't on disk → bash: scripts/publish-runtime-channel.sh: No such file or directory (exit 127). The gate/build/smoke jobs all check out; only the two publish jobs were missed in the inline→script refactor.

Caught on the first real auto-publish — the [#372] merge to pre-main ran: gate ✓, build (1.64.1) ✓, smoke macOS 14/15/26 ✓, then publish-staging failed (exit 127). So runtime-staging is still stuck at 1.63.0 (the broken-worklog runtime). Failed run

Fix

Add actions/checkout@v7 as the first step in both publish jobs — before download-artifact, because actions/checkout cleans the workspace by default and would otherwise wipe the just-downloaded dist/.

After merge

Re-triggers the workflow on pre-main; the gate still sees 1.64.1 > 1.63.0 → builds + (this time) publishes runtime-staging at 1.64.1, carrying the [#365] WORKLOG_SYSTEM fix.

Known follow-up (separate, not in this PR)

scripts/build-mlx-runtime.sh:59 fetches python-build-standalone from api.github.com unauthenticated (60/hr/IP) — it 403'd on the first attempt, cleared on rerun. Worth authenticating with GITHUB_TOKEN before the one-shot prod runtime-latest publish, where a 403 would block the fix reaching customers.
