modules: add sudo_host (CVE-2025-32462, Stratascale sudo --host policy bypass)

Second new module this cycle; sibling of sudo_chwoot (CVE-2025-32463, same Stratascale/Rich Mirch disclosure). sudo's -h/--host option — meant only to pair with -l/--list — was honored when running a command, so a sudoers rule scoped to a host other than the current machine (and not ALL) is usable via 'sudo -h <host> <cmd>' for local root. Affects sudo 1.8.8 -> 1.9.17p0; fixed 1.9.17p1. CWE-863, CVSS 8.8 (not in KEV).

detect(): version-gate [1.8.8, 1.9.17p0] via ctx->host->sudo_version (the host-restricted rule itself isn't probeable unprivileged, so VULNERABLE means 'vulnerable sudo present'). exploit(): discovers an abusable host-restricted rule from readable sudoers (or SKELETONKEY_SUDO_HOST), witnesses with 'sudo -n -h <host> id -u', pops 'sudo -h <host> /bin/bash' (SKELETONKEY_SUDO_CMD) only on a uid-0 witness; honest EXPLOIT_FAIL + operator guidance otherwise. Shared 'sudo' family; structural, arch=any; safety rank 96. auditd/sigma/falco rules, NOTICE.md (Rich Mirch / Stratascale) + MODULE.md, 4 detect() test rows.

Wiring: registry, Makefile, cve_metadata (+JSON), verify-vm/targets.yaml (ubuntu1804 sudo 1.8.21p2 target, sweep pending). Docs: README + CVES.md + docs/index.html counts 40->41 modules / 35->36 CVEs; not-yet-verified lists + corpus pill.
