Enhance Verilog digital module with additional preprocessor directive handling and connection resolution improvements

- Added support for `timescale` and `default_nettype` directives, allowing for better syntax handling in the Verilog subset.
- Introduced a mechanism for implicit named connections, improving the resolution of hierarchical names and enhancing the handling of system functions.
- Updated connection checks to differentiate between constant signals and driven ports, ensuring more accurate state management during synthesis.
- Refactored logic for handling conditional resets in state machines, improving clarity and maintainability of the reset inference process.
