Update highlighter logic, add release scripts, and bump version to 1.3.6.

- Refined cached state validation in `HighlighterEngine` to ensure row validity and buffer consistency.
- Added `make-release` and `make-app-release` scripts for streamlined release builds.
- Disabled AddressSanitizer (ASAN) by default.
- Version bump to 1.3.6.
