fix-push

Fix all reported issues, validate, commit, and push. Use when resolving feedback or pre-push verification. Use global git user for commits—never cursor/system identity. Never use --trailer for Co-authored-by or similar.

1. Fix issues: Address all errors, warnings, or feedback mentioned (lint, types, tests, reviews)
2. Validate: Run pnpm qa and resolve any failures
3. Commit: Follow steps in @.agents/skills/git-commit/SKILL.md
4. Push: git push
