dba8a31978 feat(elf): inspect Linux kernel module metadata (#7010)
* feat(elf): inspect Linux kernel module metadata

Adds inspect-kernel-module and inspect_kernel_module for ELF32/ELF64
ET_REL Linux kernel modules, read statically without executing them.
Reports ordered .modinfo entries with duplicates preserved, __versions
symbol CRCs, the presence of .gnu.linkonce.this_module and __ksymtab,
.init.text and .exit.text sizes, and an appended module signature
trailer with its PKCS#7 byte range and SHA-256. gzip, xz and zstd
containers are reported unsupported with external decompression as the
next probe. Malformed headers and exhausted entry budgets return no
partial success.

* fix(elf): bound kernel module ksymtab listing and tighten contracts

Charge listed __ksymtab* sections against max_entries, omit section names
longer than 256 bytes with ksymtab_name_exceeds_limit, and aggregate the
non-file-backed limitation so repeated huge names cannot inflate Evidence.
Use fixedTupleSchema for the signature pad bytes with projection parity
tests, and assert the late-cancellation reason and retained observation.
