 * Parse repo_url from registry to extract GitHub components.

 * - Tree path: `https://github.com/owner/repo/tree/branch/path`
 * - Blob path: `https://github.com/owner/repo/blob/branch/path`
 *
 * @example
 * ```typescript
 * // Plain repo URL
 * parseRepoUrl('https://github.com/user/skill')
 * // => { owner: 'user', repo: 'skill', path: '', branch: 'main' }
 *
 * // Monorepo skill with tree path
 * parseRepoUrl('https://github.com/ruvnet/claude-code/tree/main/skills/commit')
 * // => { owner: 'ruvnet', repo: 'claude-code', path: 'skills/commit', branch: 'main' }
