2c38becc4e feat(binary-layout): admit ELF32 i386, ARM and MIPS layout profiles (#7052)
* feat(binary-layout): admit ELF32 i386, ARM and MIPS layout profiles

inspect_binary_layout refused every ELF32 object, so router and IoT
firmware (ARM32, MIPS32) got no layout facts at all.

The pwntools adapter now admits EXEC/DYN/REL objects in these profiles:
ELF64 x86-64, ELF32 i386, ELF32 little-endian ARM and ELF32 little- or
big-endian MIPS. Header fields are read in the declared byte order, the
ELF32 header is bounds-checked at 52 bytes, and pwntools' own reported
architecture, class and byte order must match the admitted profile.
Other machines, classes and byte orders keep an unsupported_target
refusal that names the admitted profiles.

The output schema admits exactly those architecture combinations, and
the Evidence subject now names the reported machine instead of always
claiming x86_64.

verify:binary:layout cross-compiles i386, ARM, MIPS and MIPSel
executables and relocatable objects (never executed) and checks every
section name, address, offset and size against GNU readelf through CLI
and MCP. The real-binary-layout workflow installs those toolchains.

* ci(binary-layout): install target libc headers for ELF32 fixtures

--no-install-recommends skips the libc6-dev-*-cross packages the cross
compilers only recommend, so the i686 fixture fell back to the host's
/usr/include and failed to find bits/libc-header-start.h. Install the
four target libc development packages explicitly.

* fix(binary-layout): size the minimum symbol entry by ELF class

The relocation reference check required a 24-byte Elf64_Sym entry, so
every positive symbol reference in an ELF32 report was refused as
unreadable output. Elf32_Sym is 16 bytes; take the minimum from the
reported class. A 64-bit table with 16-byte entries is still refused.

morluto 8bd5ba2d23 fix(native): clarify Mach-O offset origins and reject partial ELF tables
Expose the selected Mach-O slice and its container offset, derive that identity once, and map entrypoint and nonempty segment Evidence to container coordinates. Reject relocation sections whose byte length is not divisible by the entry size instead of silently accepting a floored count.

Validation: native parser and selected-architecture boundaries, actual public CLI and stdio MCP on a compiled universal Mach-O, and a pyelftools 0.33 malformed-table probe. Full Linux pwntools bridge verification was unavailable on this host.
