Add generic hook module (x86dis + auto-sizing detour), framecrash updates, marker assets

Hook lib: port HDE32 length disassembler to Zig (x86dis.zig), add GenericHook
with automatic prologue sizing and relative instruction relocation, add
Detour(FnType) comptime-generic type-safe hook wrapper. Update build.zig
to expose x86dis, generic_hook, hook as separate modules.

Framecrash: expand vtable hook research and implementation.
Markers: updated raid marker M2 assets.
