Markus Maiwald fbb9189b59 fix(rumpk): enable user stack access and repair boot process - Enabled SUM (Supervisor Access to User Memory) in riscv_init to allow kernel loader to write to user stacks. - Removed dangerous 'csrc sstatus' in kload_phys that revoked access. - Aligned global fiber stacks to 4096 bytes to prevent unmapped page faults at stack boundaries. - Restored 'boot.o' linking to fix silent boot failure. - 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.		2026-01-08 21:38:14 +01:00
