fix: remove CLAUDE.md symlink generation from build

The CLAUDE.md symlink causes installation errors when using
`npx skills add` as it tries to copy AGENTS.md to itself.

- Remove createClaudeSymlink function from build.ts
- Remove claudeSymlink from SkillPaths interface
- Remove CLAUDE.md references from AGENTS.md structure documentation
- Delete existing CLAUDE.md symlink from skills directory
