Add Build System Warning Flags

[LinuxMainframe]

Low: Add Build System Warning Flags

Priority: LOW

Type: Build System

Location

CMakeLists.txt lines 78-82

Issue

Missing important compiler warning flags:

target_compile_options(${target} PRIVATE
    -Wall
    -Wextra
    -Wpedantic
    -Wno-unused-parameter
)

Impact

• Potential bugs might not be caught at compile time
• Missing checks for common C pitfalls
• Less portable code

Note: Some warnings (like -Wconversion) might produce many warnings initially. Consider enabling them incrementally.
