This commit adds validation logic in compiler to check for max allowed
characters per line for scripts. This allows preventing bugs caused by
limitation of terminal emulators.
Other supporting changes:
- Rename/refactor related code for clarity and better maintainability.
- Drop `I` prefix from interfaces to align with latest convention.
- Refactor CodeValidator to be functional rather than object-oriented
for simplicity.
- Refactor syntax definition construction to be functional and be part
of rule for better separation of concerns.
- Refactored validation logic to use an enum-based factory pattern for
improved maintainability and scalability.
