feat(native): inspect offline ELF layout through pwntools (#1037)

* feat(native): inspect offline ELF layout through pwntools

* fix(build): prepare offline ELF verification on clean runners

* fix(native): preserve snapshot acquisition cancellation

* fix(native): handle sectionless ELF and retain decoder diagnostics

* test(native): verify malformed symbol table entry sizes

* fix(native): respect inherited limits and unused segment fields

* fix(native): preserve packed relocations and decoder launch constraints

* fix(native): validate symbol spans and preserve resource failures

* fix(native): preserve diagnostic completeness and memory failures

* fix(native): guard bridge imports against allocation failures

* fix(native): validate relocation symbol and section references

* fix(native): retain diagnostics through compounded cleanup failures

* fix(native): preserve unresolved relocation section references

* fix(native): bound linkage evidence and preserve CPU signal diagnostics

* fix(native): preserve file-size resource failure evidence

* fix(native): retain opaque linkage names and late cancellation output

* test(native): make CPU-limit fixture robust across runners

* fix(native): verify resource failure branches before interpreting exits

* fix(native): validate declared ELF string references

* fix(native): validate section-name table before decoding

* fix(native): enforce canonical ELF name-table escapes
