Upload a file as an asset to an existing release.
Completes the publishing workflow for extension .zip packages.
Uses multipart form POST to Gitea's release assets endpoint.
Safety: 100MB cap, requires absolute file_path, supports custom
asset name (defaults to filename basename).
Closes the gap in the release workflow:
1. create_release (existing) - creates the release
2. upload_release_attachment (NEW) - uploads the .zip/binary asset
Two new tools for efficient multi-file operations:
1. get_files_batch: Fetch up to 20 files in parallel via goroutines.
Replaces N individual get_file_contents calls.
Built-in safety cap on total response size (default 500KB).
2. commit_multiple_files: Atomic multi-file commit (create/update/delete).
Uses Gitea SDK ChangeFiles API. Max 50 files per commit.
Enables proper feature commits with single git history entry.
Both tools follow Security by Design: input validation, size limits,
proper error handling, no path traversal.
Download an entire repository as zip/tar.gz in a single MCP call.
Replaces N+ get_file_contents calls when fetching whole repos.
Calls Gitea's GET /repos/{owner}/{repo}/archive/{ref}.{format} endpoint,
saves bytes to disk at output_path, returns sha256 for integrity.
Safety: 500MB cap, requires absolute output_path, parent dir auto-created.
Performance impact: ~250 calls → 1 call for typical extension repo.
