- Implemented 'fiber_can_run_on_channels' stub to satisfy Membrane linking.
- Defined kernel stack in header.zig to fix '__stack_top' undefined symbol.
- Resolved duplicate symbols in overrides.c and nexshell.
- Implemented Sovereign Syscall Table at 0x801FFF00
- Added cooperative yielding (s_yield) for Guest/Kernel concurrency
