Red Bear OS ff66b96266 observer: packet capture facility (tcpdump-like) via netcfg 
Adds packet observer with ring buffer (256 packets default):
- Observer::capture(packet) hooks into forwarding/output paths
- AtomicBool enable/disable toggle (no capture overhead when off)
- capture/count: live stats (total captured, buffered, enabled)
- capture/read: drain hex dump of buffered packets
- capture/enable|disable: toggle capture on/off

Usage:
  echo > /scheme/netcfg/capture/enable    # start capture
  cat /scheme/netcfg/capture/read         # dump captured packets (hex)
  cat /scheme/netcfg/capture/count        # stats
  echo > /scheme/netcfg/capture/disable   # stop

Mirrors Linux AF_PACKET + tcpdump facility.

Red Bear OS 2b278390ee tun: wire TUN scheme into event loop + SLAAC RS/RA protocol 
TUN integration:
- Smolnetd gains tun_scheme: TunScheme field and tun_file parameter
- on_tun_scheme_event() handler added (scheme event → poll)
- main.rs: EventSource::TunScheme, subscription, dispatch
- TUN devices can now receive and transmit packets through the netstack

SLAAC (RFC 4862):
- build_router_solicitation(): ICMPv6 Type 133 with source LL address option
- parse_router_advertisement(): ICMPv6 Type 134 with Prefix Information
  option extraction (on-link, autonomous, lifetimes)
- Slacd state machine: Idle → Solicited → Configured
  tick() drives RS retransmit (3 retries, 5s timeout)
  process_ra() extracts autonomous /64 prefixes
- ParsedRa, RaPrefix public structs for integration with IPv6 stack

Reference: Linux 7.1 ndisc_send_rs() / ndisc_router_discovery() /
addrconf_prefix_rcv()

Red Bear OS e653ef10d6 base: revert oneshot_async service types, fix local fork deps, migrate remote to RedBear-OS 
- Revert initfs/rootfs service types from oneshot_async to blocking
  Scheme/Notify/Oneshot to fix init ordering races.
- Add /scheme/pci retry loop in pcid-spawner.
- Bump redox_event to 0.4.8; use local paths for redox-ioctl and redox-rt.
- Regenerate Cargo.lock / bootstrap/Cargo.lock with only local forks.
- Update submodule origin from redbear-os-base.git to RedBear-OS.git
  branch submodule/base per single-repo policy.
