* refactor(adapters): convert adapter layer from TypeScript to JavaScript
Core framework stays TypeScript; adapter layer moves to JS-first.
Adapters are essentially "executable config + browser scripts" that
barely use TS features — this simplifies the build/distribution pipeline
by removing the dist/clis/ intermediate compilation step.
Changes:
- Convert all 753 adapter files in clis/ from .ts to .js
- Update tsconfig to exclude clis/ from compilation
- Simplify build-manifest to scan clis/*.js directly (no dist/clis/)
- Update discovery, main, fetch-adapters to load JS adapters from clis/
- Update generate-verified to output .js artifacts
- Update package.json files field: dist/clis/ → clis/
- Fix all test files for the .ts → .js transition
* fix(main): use findPackageRoot for BUILTIN_CLIS path
The previous relative path (../../clis from __dirname) only worked for
dist/src/main.js but broke dev mode (tsx src/main.ts) where __dirname
is <repo>/src — resolving to /clis instead of <repo>/clis.
Use findPackageRoot() which works for both dev and prod paths.
