fix(ci): improve nightly changelog readability and fix null issue titles (#683)

* fix(ci): improve nightly changelog readability

- Fetch issue titles individually via gh issue view (fix null titles)
- PR numbers are clickable links in Feishu card
- Closing issues shown with 📌 prefix, clearly separated from PR title
- Add GitHub Step Summary with version/baseline/changelog table
- Clean PR titles by stripping conventional commit prefix for display
- Three output formats: feishu (links), github (GFM), plain (LLM input)

* fix(ci): parallelize arm64 and x64 release builds

* fix(ci): include merge-commit PR numbers in nightly changelog

Previously only matched squash-merge format '(#123)'. Now also matches
'Merge pull request #123' format, fixing incomplete changelogs when
the commit range includes non-squash merges.
