Summary

Adds MCP tool to create repositories from GitHub templates via the/repos/{owner}/{repo}/generate API endpoint.

Why

Creating repositories from templates is more common than creating empty repositories for bootstrapping projects with standard configurations.

What changed

• AddedCreateRepositoryFromTemplate function inrepositories.go
• Registered tool inAllTools list
• Added 5 unit tests covering success and error paths
• Generated toolsnap and documentation

MCP impact

• No tool or API changes
• Tool schema or behavior changed
• New tool added

New toolcreate_repository_from_template with parameters:

• Required:template_owner,template_repo,name
• Optional:description,owner,private,include_all_branches

Prompts tested (tool changes only)

• "Create a new repo called my-app from the template github/octocat-repo-template"
• "Use template-owner/template-repo to create new-repo with all branches included"
• "Make a private repository named test-proj from owner/template"

Security / limits

• No security or limits impact
• Auth / permissions considered
• Data exposure, filtering, or token/size limits considered

Uses existing auth flow. GitHub enforces template access permissions server-side.
