Setup and doctor inspect every provider. With no GHIDRA_INSTALL_DIR and no
Ghidra launcher on PATH, the Ghidra inspection still ran the host `java` from
PATH. Its result was discarded because the configuration check already
rejects Ghidra, but its owned-process cleanup could still fail closed. In CI,
that cleanup reported cleanup_incomplete for an unrelated live process whose
/proc/<pid>/environ was unreadable, so `rea setup --client hermes` exited 1.
Run Java only for a selected installation, matching the existing rule for a
relative JAVA_HOME. Hermes setup tests now report the CLI JSON when an exit
code assertion fails.
Fixes#6200

Keep installation availability and full doctor inspection facts separate from the setup ready-provider list. A blocked Kuna cache no longer advertises deep analysis; passing unverified-version notes remain usable.
Refs #5105. All 16 focused setup and public CLI dry-run controls passed; typecheck and lint passed. Tests use a scripted Kuna version fixture and do not establish real-engine behavior. The pre-existing doctor cancellation startup-poll failure is tracked separately.
