Add session-review skill for knowledge capture

[gitlastoni]

Pull Request Summary 🚀

What does this PR do? 📝

Adds a new session-review skill that helps Claude review coding sessions to identify learnings worth persisting to project documentation.

Why is this change needed? 🤔

When working with Claude Code, valuable insights often emerge during sessions (build commands, gotchas, workflow patterns) that would benefit future sessions. This skill provides a structured way to capture that knowledge before it's lost.

How was this implemented? 🛠️

• Added .claude/skills/session-review/SKILL.md following the standard skill structure
• Skill prompts Claude to scan the session for:
  1. Project instruction updates (AGENTS.md or CLAUDE.md)
  2. Opportunities to create reusable skills

How to test or reproduce? 🧪

1. Open a Claude Code session in any project
2. Do some work that involves learning something non-obvious
3. Run /session-review
4. Verify Claude reviews the session and provides actionable output
