modules: add ghostlock (CVE-2026-43499, "GhostLock" rtmutex/futex requeue-PI stack UAF) 
Adds the ghostlock module for CVE-2026-43499 ("GhostLock", VEGA / Nebula
Security's "IonStack part II") — a ~15-year race UAF on kernel STACK memory in
the rtmutex/futex requeue-PI path (kernel/locking/rtmutex.c). On the -EDEADLK
deadlock-rollback, remove_waiter() runs against `current` instead of the waiter
task, so a concurrent sched_setattr()-driven PI-chain priority walk on another
CPU clears pi_blocked_on on the wrong task and leaves an on-stack rt_mutex_waiter
dangling. Reachable by any unprivileged user (CVSS 7.8, PR:L) — plain
futex(2) + sched_setattr(2), no userns/CONFIG beyond CONFIG_FUTEX_PI. The
corpus's first rtmutex/futex-PI module and first kernel-stack UAF (all others
are heap/slab).

Introduced 2.6.39; fixed 3bfdc63936dd (7.1-rc1), stable backports
7.0.4 / 6.18.27 / 6.12.86 / 6.6.140 / 6.1.175; 5.15/5.10/5.4/4.19 affected with
no upstream fix. CWE-416; not in KEV.

detect() is a pure version gate over the five-branch backport table. exploit()
forks an isolated child that (A) deterministically confirms the -EDEADLK
remove_waiter() rollback path is reachable (safe — no concurrent walk means no
dangling pointer; validated on real hardware) then (B) exercises the actual race
a hard-bounded 24 iters / 2s with a sibling-CPU sched_setattr(SCHED_BATCH) storm,
and stops. Deliberately under-driven: no copy_from_user widening, no stack-frame
spray/reoccupation, and the KernelSnitch leak -> forged-waiter ->
fops/ashmem/pipe R/W -> cred-patch chain (Android/Pixel-specific, per-build
offsets) is NOT bundled. Returns EXPLOIT_FAIL. Lowest --auto safety rank (11) —
a won race corrupts the kernel stack. Unlike most races it ships a real
detection signature (futex requeue-PI returning EDEADLK + sibling sched_setattr);
auditd/sigma anchor on sched_setattr, falco/eBPF on the EDEADLK tell; no yara.

Wired: registry, Makefile, safety rank 11, version 0.9.13, 9 detect() test rows
(incl. 6.13.0 -> VULNERABLE, the multi-branch "newer than all" case), CVE
metadata (CWE-416 / T1068 / not-KEV; cve_metadata.c + KEV_CROSSREF.md regenerated
-> 13 of 40), README + CVES.md + website counts (45 modules / 40 CVEs),
RELEASE_NOTES v0.9.13, verify-vm target. Also corrects pre-existing
docs/index.html drift left by v0.9.12 (body counts stuck at 43/38 and a missing
bad_epoll corpus pill). Tests: 33 kernel_range + 101 detect, all pass.

upstream fix 3bfdc63936dd (Keenan Dong / Thomas Gleixner).
