0.1.8: the shipped binaries run from a bare checkout
The Action runs node dist/cli.js from the checked-out tag, and tsup had been externalising the runtime dependencies, so on a runner with only the checkout it died with ERR_MODULE_NOT_FOUND. Both binaries vendor their dependencies now, with a createRequire shim for the CommonJS ones.
Verified the way the runner does it: dist/ and package.json copied into a directory with no node_modules at all, CLI and MCP handshake run from there.
