`detect` command (`attack_surface_approximation`) fails on stripped binaries and non-standard Ghidra syntax

[krpandrei05]

The detect command is unable to analyze stripped binaries or complex executables due to a combination of missing symbols and non-standard decompilation output.

Currently, the tool encounters two main obstacles:

1. Missing Symbols: The Ghidra script crashes when the main function is not found, resulting in a Python traceback. pycparser then attempts to parse this traceback as C code, leading to a ParseError (e.g., "before: recent").
2. Decompilation Artifacts: The decompiled code often contains Ghidra-specific keywords and formatting (such as processEntry, PTR_FUN_, or &stack0x...) that are not valid C89 syntax, causing further parsing failures.

The static analysis should be robust enough to fall back to the entry point and clean the code of any non-standard artifacts before passing it to the C parser.

Steps to reproduce:

1. Use a stripped ELF binary (e.g., a system utility like uname).
2. Run:

poetry run attack_surface_approximation detect --elf examples/uname_32

The result is:

$ poetry run attack_surface_approximation detect --elf examples/uname_32
