CppVtableReconstructorAnalyzer: ET_EXEC fix + generic consumer tracing for LoongArch64/MIPS/PPC.

Bug fixes:

  • _check_itanium_header: was using vtable_va as a raw file byte index; correct only for ET_DYN
    (PIE, VA≈0) — always returned False for ET_EXEC (non-PIE, VA=0x400000+). Fixed: new
    _va_to_file_offset(va) helper converts VA → file offset via section headers.
  • _trace_arm64: self._data[text_va:] sliced by VA not file offset; empty on ET_EXEC. Fixed:
    self._data[text_off:] using text_sec.offset.

Enhancements:

  • _trace_generic: arch-agnostic consumer tracer that scans .text for the vtable VA as a
    pointer-sized literal (LE/BE from EI_DATA; width 4 for ppc32, 8 otherwise). Runs on
    LoongArch64, MIPS, PPC32, PPC64, RISC-V, and any future arch. x86-64 and ARM64 still use
    full ISA-specific tracers.
  • Removed "IDAPython" / "IDA" references from module docstring; emit_ida_script() generates a
    type-annotation + comment script with no external tool dependency.
