3 people 31772b3818 cfw: Add opt-in --force-exc-guard for the EXC_GUARD Mach-port-guard patch ...

On 26.x bases the EXC_GUARD (Mach port guard) disable patch is not required
to boot, so it is no longer applied unconditionally on regular/jb/exp.
Production apps shipping crash-reporting/RASP SDKs (Bugly, Crashlytics,
KSCrash) call task_swap_exception_ports(), which the research kernel enforces
as a fatal GUARD_TYPE_MACH_PORT violation on launch; a --force-exc-guard flag
(FORCE_EXC_GUARD=1 in the Makefile) re-enables the patch for those cases.

iOS 18 bases and the dev variant keep the patch always-on, since both need it
to boot. The documented violation is corrected from SET_EXCEPTION_BEHAVIOR to
KOBJECT_REPLY_PORT_SEMANTICS, matching the actual reproduction crash logs.

Also add /vm-*/ to .gitignore for multi-VM directories.
