feat(finalize-pr): add Phase 4 to auto-update PR metadata

[JacobPEvans]

Summary

• Adds Phase 4 (Update PR Metadata) between pre-handoff verification and the ready report
• Phase 4 delegates to a haiku subagent for token efficiency — uses compact git log --oneline + git diff --stat instead of full diff
• Sub-steps 4.1 (title/description) and 4.2 (linked issues/PRs) can run in parallel within the agent
• Former Phase 4 (Report Ready Status) becomes Phase 5
• /squash-merge-pr is now marked optional since finalize-pr handles metadata itself

Changes

• github-workflows/skills/finalize-pr/SKILL.md: Added Phase 4, renumbered Phase 5, updated critical rule 9, updated workflow diagram

Test Plan

• Read SKILL.md — integer-only phase numbering at top level (1–5)
• Sub-steps use X.Y notation (4.1, 4.2) and are marked as parallel
• Workflow diagram matches new 5-phase structure
• /squash-merge-pr still referenced as optional in Phase 5

• Updated critical rule 9 from "Report ready and pause" to "Update PR metadata automatically"
• Updated workflow diagram to reflect 5-phase structure
• Uses token-efficient approach with git log --oneline and git diff --stat instead of full diffs
• All changes follow repository conventions for integer-only top-level phase numbering and X.Y sub-step notation
