feat: redbear-mini boots to login prompt with Phase 0 threading patches
Kernel (local/sources/kernel):
- Per-CPU idle context race fix (try_idle_context)
- Pinned to nightly-2026-04-11
- Futex sharding, cache-affine context, per-CPU scheduler
- NUMA topology, proc lock ordering, sched policy handles
- ACPI FADT type fix
relibc (local/sources/relibc):
- Non-robust mutex ENOTRECOVERABLE false positive fix
- pthread_cond_signal POSIX fix
- Pthread yield, barrier SMP futex, robust mutexes
- sched API, comprehensive semaphore, pthread affinity+setname
- stdint.h in sched.h cbindgen
Boot verified: UEFI -> kernel -> init -> drivers -> services -> login prompt
All Red Bear init stages pass (02->04->06->08)
xhcid no longer crashes, D-Bus services online
