Adds manifest.json with user_config prompts for printer connection settings, .mcpbignore, an npm package:mcpb script, and a release-mcpb CI workflow that attaches the packed bundle to tagged GitHub releases, so the server can be installed via Claude Desktop's extension UI instead of hand-editing JSON config.

TEMP_DIR defaulted to a cwd-relative path, but the extension host spawns the server with a cwd we don't control (and may not be writable), so the module-load-time mkdirSync threw and killed the process before it ever opened the stdio transport -- surfacing only as a silent "Server transport closed unexpectedly" moments after initialize. Default to os.tmpdir() instead, and add top-level uncaughtException/unhandledRejection handlers so any future crash logs a stack trace instead of dying silently.
