CLI dist/cli/main.js file is missing #!/usr/bin/env node at the very top. This causes pnpm happo to fail on systems where pnpm install prefers symlinking instead of creating command shims, e.g. macOS.

Steps to repro —

1. pnpm install [email protected]
2. pnpm happo

/node_modules/.bin/happo: line 1: import: command not found
/node_modules/.bin/happo: line 2: startServer: command not found
/node_modules/.bin/happo: line 3: syntax error near unexpected token `}'
/node_modules/.bin/happo: line 3: `} from "./chunk-JTRP4JVC.js";'

Cross-platform workarounds:

1. Directly-running script: node node_modules/happo/dist/cli/main.js
2. Forcing PNPM to create command shims:

// pnpm-workspace.yaml
preferSymlinkedExecutables: false

Seems to have originated in #311.
