Goal

Move /Users/zbeyens/git/slate-v2/packages/slate-history/test fully onto Bun and remove the last Mocha lane from the repo.

Findings

• packages/slate-history/test/index.js had the same problem the old slate entry had: fixtures imported jsx from it while it also bootstrapped the whole suite
• the package only needs two fixture groups:
  • undo
  • isHistory
• one package-local Bun entry is enough to replace the Mocha harness

Plan

1. Turn packages/slate-history/test/index.js into a pure helper export
2. Add one Bun suite entry for the full slate-history fixture corpus
3. Switch package and root scripts so Mocha is gone entirely
4. Verify package build, typecheck, lint, Bun, and root test flow

Verification

• pnpm --filter slate-history test
• pnpm turbo build --filter=./packages/slate-history
• pnpm turbo typecheck --filter=./packages/slate-history
• pnpm lint:fix
• pnpm typecheck
• pnpm test
