Ariel Fikru Avicennaandgensokyo-dev cab78de506 feat(ghidra): analyze GameCube/Wii DOL executables through Ghidra (#6240)
* feat(domain): parse and validate GameCube/Wii DOL headers

Add a pure parser for the 0x100-byte DOL header (7 text and 11 data
slots, BSS, entry point). Used slots must lie after the header and
inside the file and the 0x80000000..0x81800000 load window; text slots
are 4-byte aligned; sections may not overlap in memory or in the file;
the entry point must be inside a text section. BSS may overlap data
sections, as .sdata/.sdata2 do in shipped DOLs.

Refs #1741

* feat(binary): admit caller-selected GameCube/Wii DOL targets

* feat(ghidra): import GameCube/Wii DOL targets through a section-map pre-script

* test(ghidra): cover DOL launcher arguments, attestation and raw profile digests

* test(ghidra): add the real verify:ghidra:dol lane and DOL docs

* fix(ghidra): read only the DOL header and section ranges instead of the whole file

* test(ghidra): derive DOL lane addresses from readelf and admit Gekko from the install catalog

* fix(ghidra): attest DOL block permissions, space, overlay and load state

* fix(ghidra): keep load-image permissions optional for older inspections

* fix(contracts): accept DOL targets in binary_session output

* fix(ghidra): adapt the DOL lane to the current upstream address schema

Validate DOL load-image coordinates with the upstream observed-address
schema, drop a duplicate import left by the rebase, and re-pin the raw
profile digests to the unmodified upstream resolver.

* fix(ghidra): preserve bridge inventory symbol provenance

* fix(ghidra): align DOL verification with shared workflow contracts

Ariel Fikru Avicennaandmorluto c86b09a109 feat(ghidra): admit 32-bit big-endian PowerPC ELF (#1747)
* feat(ghidra): admit 32-bit big-endian PowerPC ELF

Recognize EM_PPC as a provider-neutral `powerpc` family that keeps its ELF
class, byte order, type and flags, and admit ELF32 big-endian ET_EXEC through
a bounded Ghidra lane. ELF64, little-endian, relocatable/shared objects and
EF_PPC_EMB are refused with a specific reason; Hopper and IDA do not gain
PowerPC support, and Windows Ghidra P0 is unchanged.

Ghidra's ELF loader selects PowerPC:BE:32:e500:default for a plain EM_PPC
header, which misreads 750-family code. The lane binds
PowerPC:BE:32:default/default in the profile (language_selection
"admitted-lane-v1"), imports with it and checks the reported language. A
language set through REA_GHIDRA_LANGUAGE_ID still replaces the lane default.

Add a source-owned fixture, fixed-encoding probe, GNU readelf cross-check and
the optional `verify:ghidra:ppc` real-provider lane, plus docs/ghidra-ppc.md.

Refs #1741

* style(ghidra): format shared PowerPC profile integration

* fix(ghidra): preserve caller-selected PowerPC languages
