* [AI] Extract PR/commit rules into shared agent skill
Deduplicate PR and commit instructions from AGENTS.md into a standalone
skill file at .github/agents/pr-and-commit-rules.md. This single source
of truth is consumed by both Claude Code (via CLAUDE.md @-import) and
Cursor (via .cursor/rules/pr-and-commit.mdc with alwaysApply: true).
AGENTS.md now references the shared file instead of repeating the rules
in three separate sections.
