Replace zip tool with gzip for single file compression

- Changed tool from multi-file zip to single-file gzip compression - Replaced JSZip dependency with node:zlib (built-in) - Updated schema: renamed ZipResourcesInputSchema to GzipResourceInputSchema - Tool now accepts single file with name and data URI parameters - Updated tool name from ZIP_RESOURCES to GZIP_RESOURCE - Updated environment variables (ZIP_* to GZIP_*) - Removed jszip from package.json dependencies 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
