feat(kernel): derivation-tree revocation, region caps
...
- caps record parent (mint/delegate/ipc), CapRef w/ pid+slot gens
- Revoke = delete subtree, keep self; drop/death re-parents children
- CreateRegion/MapRegion; mapping lives only as long as its cap
- drop Permission::Revoke + object-wide revoke
- mint any cap (badge only ep/ntfn), process caps delegable
- kani: descendants == subtree; model-based fuzz vs spec

feat(kernel): seL4-style IPC, notifications, status ABI
...
- badges + Mint, Call/Reply/ReplyRecv w/ gen-checked reply slot
- cap transfer (1/msg, copy, needs Delegate, rechecked at delivery)
- notifications: signal/wait/poll/bind, irq -> notification routing
- WaitAny/WaitForInterrupt removed; a0=status, ErrorCode
- libkos: single ecall primitive, compat wrappers + typed new api
- fix: trap return clobbered user t0 on every trap
- fix: wait queues FIFO, delegate keeps badge, fault cap checked
- docs/ipc.md spec, ipc tests, ipc fuzz, kani ntfn + waitqueue

feat(kernel): object lifetimes via slot generations
...
- SlotGenerations per table, never wraps, retires exhausted slots
- caps to dead/reused process, endpoint, region rejected
- endpoints owned, die w/ owner, waiters woken w/ error
- DropCap syscall + libkos wrapper
- irq table bounds-checked, routes dropped w/ thread
- self-kill terminates caller, exit_thread full cleanup
- sched run_now: switch to named thread, not queue head
- lifetime tests, fuzz kills/recreates, kani gen proofs
