Fix composite build: re-export KeyboardResultType, exclude tests, remove stray emits

- Export KeyboardResultType as value from Types (const enum)
- Exclude browser unit tests from composite build
- Drop test/benchmark from tsconfig.all (uses path imports to sources)
- Update TaskQueue import paths in browser and addon-webgl
- Remove accidental .js/.d.ts emit files from src/
