- Add @wasm-fmt/ruff_fmt as devDependency for build-time bundling - Add static import hint in main.ts so ncc can detect the package - Bundle WASM binary (ruff_fmt_bg.wasm) to dist for runtime usage - Add Jest mock to prevent test failures with ESM-only package This fixes the "Cannot find package '@wasm-fmt/ruff_fmt'" error that occurred when gitstream-core 2.1.216+ tried to initialize Python formatting. The solution works for both environments: - GitHub Actions: WASM bundled by ncc, loaded via dynamic import - Lambda: WASM loaded from node_modules via dynamic import 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>

Summary
Fixes a runtime error where the GitHub Action failed with "Cannot find package '@wasm-fmt/ruff_fmt'" when using gitstream-core 2.1.216 or later.
What Changed
When gitstream-core added WASM-based Python formatting support, the GitHub Action couldn't find the required WASM package at runtime because it wasn't being bundled by ncc.
