refactor(pe): share optional-header structural facts

Decode optional-header declarations once and pass detached directory words, locations and SizeOfHeaders to native consumers. Preserve executable machine admission, raw GPU/resource machine reporting, RVA mapping and certificate file-offset semantics.

Validation: fresh build/catalog, full static checks, 466 core/provider fixture tests, 122 workflow tests and 14 selected file-backed PE admission tests passed. Public CLI and actual stdio MCP used authored artifacts; installed external providers were not qualified. Added 17 structural cases and two GPU machine-policy controls. Eager directory decoding costs remain unmeasured.
