New package: @bust/eslint-config

[busticated]

Description

Adds @bust/eslint-config — an ESLint flat-config factory which targets TypeScript with type-aware rules by default. It takes typescript: false for JS-only projects, and turns React, Vitest, and node:test support on by option. Also fixes the changelog:show developer script, which crashed on any package with no release tag in this repo.

Note

This replaces the ancient busticated/bust-eslint-config repo + codebase

How to Test

1. Clone and setup this branch locally (docs)
2. Run unit tests: npm test
3. Run end-to-end tests: npm run test:e2e
4. Check the fixed command against a package that has never been released here:
   • npm run changelog:show -- --workspace packages/eslint-config
   • then against one that has: npm run changelog:show -- --workspace packages/timer
5. Inspect what the shared config resolves to: npx eslint --inspect-config

Outcome

All tests pass and the repo lints clean through the shared config. changelog:show reports every change so far for the unreleased package and since @bust/timer@2.0.1 for the released one, rather than dumping a git error. Every block the config contributes shows up named bust/* in the inspector.
