[AAASM-2324] 🐛 (ci): Replace deprecated macos-13 with macos-15-intel runner

[Chisanan232]

Description

GitHub deprecated macos-13 on 2025-09-19. Jobs requesting runs-on: macos-13 stay queued forever with no runner picking them up. Surfaced when v0.0.1-alpha.3's build-macos-x86_64 wheel job was stuck queued, blocking the publish job until manually cancelled.

Fix

Single-line change: macos-13 → macos-15-intel (current GA Intel macOS runner; more battle-tested than newer macos-26-intel).

CI state

7 SUCCESS + 6 SKIPPED, 0 failures — mergeable=MERGEABLE, mergeStateStatus=CLEAN. The 6 SKIPPED are the by-design Complete Release Validation Process steps that only fire on tag-push (docs-build, Docker validate, supply-chain scan, etc.) — same intentional-skip pattern as previous python-sdk PRs.

The actionlint warning about unknown label macos-13 that was present on PRs #67/#68/#69 is now GONE — the label was the bug, now fixed.

Implementation choice notes

Why macos-15-intel over macos-26-intel: Apple ships new macOS major versions yearly; macos-26-intel is the newest available but less battle-tested. macos-15-intel is the previous-stable Intel runner — more reliable for release CD where stability beats novelty. If macos-15-intel is itself sunset in the future (Apple's discontinuing Intel macOS support trajectory), bump to whatever the latest GA Intel label is.

Verdict

Ready for human approval and merge. The reviewer-miss called out in the original PR body (I called the warning "pre-existing unrelated" on PRs #67/#68/#69) is an honest disclosure — this is a real fix for a real release-blocker.
