Ports the verified freebsd-update-reboot.md (reboot-needed detection, pre/post
status capture, package/service notes, vuln-audit wording) from clawdie-ai into
a layered-soul skill, alongside the existing freebsd-* operational skills.
SKILL.md wraps it as the same-major upgrade procedure (15.0 -> 15.1): ABI
FreeBSD:15:amd64 unchanged so no package rebuild / no PG dump-restore; reboot
only on operator go-ahead; build-host-first sequence; and the clawdie-iso side
(bump/override FREEBSD_VERSION, version-agnostic docs). Escalation is
host-agnostic (mdo on the operator image, sudo/doas elsewhere).
Validation-evidence slot left for the real OSA 15.0->15.1 run to fold in.
