feat(skills): add finishing-a-development-branch skill

[JeremyDev87]

Summary

• Add new finishing-a-development-branch skill at packages/rules/.ai-rules/skills/finishing-a-development-branch/SKILL.md
• Decision tree guiding merge directly vs create PR vs cleanup/abandon
• Pre-completion checklist: tests pass, no type errors, clean git status, branch up to date
• Post-merge cleanup steps with worktree-aware ordering (remove worktree before deleting branch)
• v2.0 frontmatter with disable-model-invocation: true for safety
• Graphviz dot decision tree, common rationalizations table, red flags section

Test plan

• markdownlint passes (0 errors)
• File under 500-line skill limit (282 lines)
• Frontmatter valid (name, description, disable-model-invocation)
• Dot graph syntax verified (no phantom nodes, all edges connected)
• Git commands use safe defaults (-d not -D, --force-with-lease not --force)
• EVAL phase: 0 Critical, 0 High, 0 Medium issues

Closes #796
