chore: remove .claude directory and add to .gitignore

[matthew-dean]

Summary

• Removes .claude/ directory (agent specs, settings) from the repo
• Adds .claude/ to .gitignore so local configs aren't tracked

These files were accidentally committed in #4414 and aren't project-critical.

Summary by CodeRabbit

• Chores
  • Removed an internal, specification-driven workflow framework and related agent/specification artifacts used for design, requirements, tasks, implementation, judging, and testing.
  • Removed associated system prompt and configuration that orchestrated that workflow.
  • Updated version control and CI settings to ignore internal/generated development artifacts and directories.

Poem

🐇 Files once full of plans and charts,

now quietly removed in quiet parts.
A rabbit hops, no spec to bind,
leaving gentle traces in .gitignore behind.
Huzzah for tidy roots and springtime finds.
