kernel(config): seanfarm33 — forensics/recovery adds, verified trims ... 02d0f2c85e

Adds (wedge posture = panic + auto-reboot, decided 2026-08-15): pstore
with ramoops, softlockup/hardlockup (buddy) and hung-task detectors that
panic, panic_on_oops, softdog. A wedged node now reboots itself in
minutes and leaves a trace; node 069094 sat Ready-but-dead with zero
evidence for want of these.

Adds (observability + memory): PSI, task delay accounting, MGLRU,
THP default madvise (Postgres/etcd latency; Mayastor hugetlbfs is
explicit and untouched).

Security: compile the lockdown LSM the LSM list already named (it was
inert), dmesg_restrict, random_kmalloc_caches, bug_on_data_corruption.

Drops, each verified against the live config, the QEMU Q35 hardware,
and the deployed stack: KVM host support, kexec/kdump (never had
crashkernel=; bootc reboots via firmware), IKHEADERS, Intel MEI,
cpufreq, ipip/sit tunnels (cilium is vxlan), LDT/16-bit/vsyscall,
/dev/mem, /dev/port, BSD ptys, AppArmor (no userspace on Alma), and
geneve/macvlan/macvtap/vlan/bridge. WireGuard STAYS: cilium node
encryption is live. DUMMY stays: nodelocal-dns uses it.
