Bundle CLI to eliminate dependency conflicts

[marcospassos]

Summary

The CLI was published with all runtime dependencies externalized, so installing it pulled ~50 transitive packages into the host project's node_modules and caused frequent version conflicts (notably around Babel and Zod).

This PR ships the CLI as a single self-contained bundle. Consumers now install one package with zero transitive dependencies.

Bundle size

Step	Size
Before (deps externalized)	420 KB shim + ~50 transitive packages
Bundled, all deps inlined	2.86 MB
+ emoji regex / esprima / browserslist stubs	2.31 MB
