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

feat(kernel): kernel-owned memory model
...
- FrameTable: per-frame owner/use, replaces PagePool + ProcessMemory
- Quota per process, page tables charged to owner
- Regions for shared mem + device MMIO, torn down w/ owner
- Platform: create/destroy AS, map/unmap, zero_frame; drop translate_va
- RequestPages/ReleasePages/MapPage(move) checked vs kernel records
- user window 0x1000..32MiB, private pts by construction
- boot loader + device setup go through kernel api
- kernel built in place, boot allocator bounded
- isolation tests, randomized invariant test, FrameTable kani proofs
- fixes: inflated release, unmapped release, dst va unchecked,
heap overflow, unbounded pt alloc, unzeroed frames, double free

fix: sched round-robin, cap slot OOB panic, clippy, make ci
...
- RunList -> intrusive FIFO, no starvation, no silent drop
- cap table sized to CapSlot range (kani caught OOB panic)
- snake food color test uses const
- kani cfg lint, RUST_MIN_STACK for big kernel struct in tests
