Standardize FFI Implementation

Description

Remove usage of Peek and Poke in .hsc files and standardize FFI to use function calls only. This requires modifying the C code to provide proper getters and setters for memory access.

Requirements

• Remove Peek/Poke usage from .hsc files
• Add getter/setter functions in tinywl.c
• Update FFI bindings to use new functions
• Ensure consistent memory access patterns

Acceptance Criteria

• No more Peek/Poke usage in Haskell code
• All memory access done through proper FFI function calls
• Consistent getter/setter implementation in C code
• All .hsc files converted to standard FFI approach
