Entrpi 250dc81cd6 fix: correct stale provider refusal and diagnostic text (#7484)
* fix(ghidra): name every admitted family in the architecture refusal

The refusal listed x86, x86_64, arm, arm64, MIPS, RISC-V, raw 6502 and
raw m68k, but the admission set also holds powerpc and hexagon. Build
the text from SUPPORTED_ARCHITECTURES, marking raw-only families, so a
newly admitted family cannot be left out again, and name the refused
family.

* fix(hopper): stop calling the Ghidra Hexagon lane verified

Hopper declined Hexagon targets with "Select a verified Ghidra Hexagon
profile instead", but REA has no verified Hexagon lane. Record whether
each declined family's Ghidra lane is verified, and say that Ghidra
admits Hexagon through an unverified lane.

Name declined families by architecture id, as the Ghidra and IDA
refusals do.

* fix(ghidra): name the pinned language in profile readback refusals

The session readback said "MIPS" whenever a provider-pinned profile
conflicted with the target or with REA_GHIDRA_LANGUAGE_ID, although the
RISC-V, PowerPC and DOL lanes are pinned too. The readback helper was
MIPS-named and re-parsed the language slot that
ghidraProfileLanguageOverride already owns. Move it beside that owner as
a family-neutral readback and name the pinned language id instead.

* fix(ghidra): list DOL among independently verified load images

GameCube DOL load images are independently verified, but the declined
format reason, the inspect_native_load_image capability note and the
Windows P0 guide listed only DOS MZ, DOS COM and raw-binary.

* fix(ghidra): count RV32E's sixteen integer registers

The EF_RISCV_RVE refusal described a 15-register ABI. RV32E has 16
integer registers, x0-x15, as docs/ghidra-riscv.md already says.

* fix(elf): name the refused e_machine

"unsupported ELF architecture" did not say which machine was refused.
Include the numeric e_machine, for example EM_XTENSA 94.

* test(hopper): assert declined-lane facts and owned refusal reasons

The MIPS case banned the phrase "not verified" instead of checking
facts, so wrong advice would still pass. Expose each declined family's
Ghidra lane status, assert those statuses, check that the advice depends
on the status, and compare Hopper's refusals with
hopperDeclinedArchitectureReason. The RISC-V refusal table now compares
the provider's reason with ghidraRiscvUnsupportedReason and expects the
EF_RISCV_RVE declaration name rather than fixed wording.

* test(ghidra): assert verified load-image formats as owned facts

The declined-format test required display phrases such as "DOS MZ" and
"GameCube DOL", so harmless rewording failed it while wrong guidance
containing those names passed. The format list was also spelled three
times: in the attestation's membership check, its reason and the
inspect_native_load_image capability note. Give the verified formats one
owner with the formatters for both texts, assert the list as a fact, and
compare the delivered reason and capability note with those formatters.

* fix(hopper): stop restating which Ghidra lanes REA has verified

Hopper's refusal for families it declines carried its own table of
which Ghidra lanes REA has verified (mips, riscv and powerpc verified,
hexagon not). That restated the Ghidra provider's facts in Hopper and
goes stale whenever they change, the drift that made the Hexagon refusal
wrong in the first place. Reading Ghidra's facts from Hopper would
couple the providers instead; no module in src/hopper imports from
src/ghidra.

The table and hopperDeclinedGhidraLane are removed.
hopperDeclinedArchitectureReason now states only what Hopper owns: it
does not admit the family, and the Ghidra provider's lane reports
whether REA has verified it. The arm64_32 sentence is unchanged.

The test checks every declined family against the formatter: each
reason names the family and Ghidra, and apart from the name all reasons
are the same text, so none states a per-family Ghidra status.

* fix(hopper): route declined families to Ghidra without promising its lane facts

The refusal said the Ghidra lane reports whether REA has verified it, but
Ghidra admits Hexagon with no such note, so a caller could not find the
promised status. Hopper now only states that it does not admit the family
and routes the caller to the Ghidra provider.
