Goal

Remove manifest dependencies in /Users/zbeyens/git/slate-v2 that no longer have a real source, config, script, or build owner.

Findings

• root already carried dead Babel/Jest-era tooling after the Bun/Vitest cut
• package-level source-map-loader residue remained in several packages with no current owner
• slate-dom still had a zombie test script despite having no test/ tree
• slate-react still carried a few duplicate or stale test/dev deps after the Vitest migration

Planned Cuts

1. remove dead root tooling deps
2. remove dead package-local Babel/source-map/test baggage
3. keep only deps with live source/config/script ownership
4. refresh lockfile
5. rerun bun check
