Parse NT_PRSTATUS, NT_PRPSINFO, and NT_AUXV notes from the core file ELF headers (both 32-bit and 64-bit layouts) and use them as fallbacks in CoredumpSource when the corresponding systemd journal fields are unavailable. This enables extracting process stat, status, comm, cmdline, auxv, word size, and byte order directly from minimal core dumps that lack journal metadata. Also add ByteOrder::u16/u32/u64 endian-aware conversion helpers and extract signal_bitmask_to_set for reuse from raw u64 signal masks. Co-Authored-By: Claude Opus 4.6 <[email protected]>
