Implemented a capture flag in `Ask262Debug` to enable/disable marking.
- Added `_captureEnabled` property and related logic in `mark()`.
- Introduced `startTrace()` and `stopTrace()` methods to toggle capture.
- Updated verification script to start tracing, run tests, stop tracing, and assert that the `Array.prototype.every` section is captured and marked important.
- Moved `verify-ask262-debug.mts` from `scripts` to `lib-src/node`.
- Updated import to use `#self` alias.
- Added npm script `verify-ask262` to run the verification script.
- Adjusted `scripts/tsconfig.json` to include the new file location.
Restore original formatting in engine262 folder:
- unicode.d.ts: revert to 4-space indentation, single quotes
- syntax-error.d.ts: revert to 4-space indentation, remove semicolons
Biome should not format files in engine262/ as it's excluded in biome.json.
