feat: add export database and import record decoding (M7)

- New src/exports.rs: embeds doc/xbox360_exports.md via include_str!
  and lazily parses it into a lookup table (OnceLock). Covers 2,913
  exports across xboxkrnl.exe, xam.xex, and xbdm.xex.
- New src/imports.rs: decodes import records from extracted PE images
  by reading the u32 at each import address, extracting record type
  (variable/thunk) and ordinal, and resolving against the export DB.
- inspect command now shows a full resolved imports table with names.
