chore(skills): Add .agents symlink for Claude skills

[adinauer]

📜 Description

Add a project-local .agents/skills symlink to .claude/skills.

This allows pi to discover repo skills using its built-in .agents/skills project discovery path without requiring a per-repo .pi/settings.json.

💡 Motivation and Context

We want repository-scoped skill discovery without globally loading skills from unrelated repositories and without editing settings in each repo.

Using .agents/skills keeps discovery local to the current repository while continuing to author skills under .claude/skills.

💚 How did you test it?

• Ran ./gradlew spotlessApply apiDump successfully.
• Verified symlink target: .agents/skills -> ../.claude/skills.

📝 Checklist

• I added GH Issue ID & Linear ID
• I added tests to verify the changes.
• No new PII added or SDK only sends newly added PII if sendDefaultPII is enabled.
• I updated the docs if needed.
• I updated the wizard if needed.
• Review from the native team if needed.
• No breaking change or entry added to the changelog.
• No breaking change for hybrid SDKs or communicated to hybrid SDKs.

🔮 Next steps

• If desired, replicate this symlink pattern in other repos that keep skills under .claude/skills.
