refactor(ai): collapse .claude bridge back to 3 directory symlinks

Per request: a single symlink per top-level dir, not one per skill.

  .claude/skills   -> ../.agents/skills
  .claude/commands -> ../.agents/commands
  .claude/rules    -> ../.agents/rules

Target is '../.agents/...' so it resolves relative to .claude/. The
12 skills under .agents/skills/ remain discoverable through the
single bridge.
