feat(pe): inspect import and delay-load tables (#6509)

* feat(pe): inspect import and delay-load tables Add inspect_pe_imports / inspect-pe-imports to read PE32/PE32+ import and delay-load directories without executing the image. The report keeps DLL names, named and ordinal functions, ILT/IAT RVAs, and a pefile import hash of the standard import table. A missing directory is observed absence, not proof the image never imported APIs. * fix(pe): default PE import fixture options Allow peImportImage() without an argument so CLI and filesystem tests can use the KERNEL32 sample without repeating an empty options object. * test(pe): keep import path cases on the dedicated MCP contract inspect_pe_imports already rejects relative MCP paths in its own boundary test. Leave the shared absolute-path matrix to tools whose handler issue projection matches that suite's expected shape. * fix(native): index virtual-to-file mapping lookups mappedFileOffset scans every mapping twice per span, so a parser that translates one span per table entry costs sections x entries. Add fileMappingLookup, which builds an O(n log n) interval index once and answers each span in O(log n) with the same accept, reject and translation results. A differential test checks it against mappedFileOffset over randomized overlapping mappings and zero fills.

Delay-load issues do not withhold it. - Hash ordinal imports with pefile's complete ordlookup tables and its ord<decimal> fallback instead of declining unmapped ordinals. - Report a nonterminal descriptor whose FirstThunk is zero, and a delay-load descriptor whose IAT or INT RVA is zero, as malformed_entry partial coverage instead of a complete empty inventory. - Directory evidence lists the file spans actually consumed for the descriptor array and terminator; discontiguous mappings produce separate spans and separate Evidence ranges. - Carry exhausted limits as PeImportLimitFailure.limit and derive recovery from it; the fixed 16 MiB retained-text ceiling reports a fixed allowance instead of max_file_bytes advice. - Translate RVAs through the indexed mapping lookup and yield with a cancellation check every 1024 table entries.
