fix(ci): find the pending release by label instead of by page

[mogita]

Ticket

CHA-2963

Problem

detect listed one page of closed PRs and filtered the autorelease: pending label client-side, then took .[0]. A pending release that has slipped past those 50 reads as "nothing to release", so the run skips the suite and the tag and exits green. The release silently never happens.

This is the last of the six SDKs still on that query; the same fix went into getstream-go in #162.

Solution

Brings the job to the shape the other five share. The Find a merged Release PR waiting to be tagged step is now byte-identical to stream-sdk-java's:

• Query the label server-side through /issues, then confirm each candidate is merged and on this base branch. No paging assumption, and a hotfix branch's pending release no longer masks this one.
• Add a ready output: pending and tagged at this run's own commit. The suite runs on github.sha while the tag lands on the Release PR's merge commit, so gating the irreversible half on ready is what makes "tested what we tag" true.
• On a mismatch, warn and stand down instead of failing. The old Refuse to tag a commit the suite did not run on step hard-failed, which reddens every later push to main until someone clears it; that step is now redundant and is removed.
• release-pr gates on pending != 'true', so a second Release PR is not proposed while one is merged and waiting to be tagged.

How to verify

1. On a normal push, Detect pending release prints No pending release on main and only Release PR runs.
2. On the push of a merged Release PR, it prints Pending release #N will be tagged at <sha>, both test jobs run, then 🚀 Tag and release.
3. A failing suite leaves the tag uncreated, and the merged Release PR keeps its autorelease: pending label for the re-run.

Summary by CodeRabbit

• Release Process
  • Release checks now identify pending releases and verify they match the current branch commit before proceeding.
  • Testing and tagging are limited to releases confirmed as ready.
  • New release creation is skipped while another release remains pending.
  • Releases with mismatched commits remain pending and display a warning.

📝 Walkthrough

Walkthrough

The release workflow now detects pending Release PRs, validates their merge commit against the workflow commit, and exposes a readiness status. Release PR creation, tests, and tagging use this status.

Changes

Release readiness gating

Layer / File(s)	Summary
Detect and validate release readiness .github/workflows/release.yml	The detect job queries closed issues labeled autorelease: pending, selects the first merged PR for the current branch, compares its merge SHA with github.sha, and exports pending and ready.
Gate release jobs on readiness .github/workflows/release.yml	Release PR creation is skipped when a pending release exists. Unit tests, integration tests, and tagging run only when ready == 'true'. The previous pre-tag SHA validation step is removed.

Priority: ⬇️ Low

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

Merge Risk: 🟡 Moderate · up to ebfda

A pending release can be missed when other branches have enough pending releases, allowing a duplicate Release PR to be created. Paginate the query before merging.
