tcp: extend TcpInfo with send/recv queue, congestion window, MSS
...
TCP_INFO socket option now returns real-time connection metrics:
- tcpi_snd_queuelen: bytes queued for transmission
- tcpi_rcv_queuelen: bytes waiting in receive buffer
- tcpi_snd_cwnd: send capacity (congestion window proxy)
- tcpi_rcv_wnd: receive capacity (advertised window proxy)
- tcpi_snd_mss: maximum segment size (1460 for Ethernet)
- tcpi_state, tcpi_rto preserved from prior version
Struct layout: #[repr(C)] 28 bytes, compatible with Linux TCP_INFO consumers.

udp: socket option completeness — SO_REUSEADDR, SO_BROADCAST, IP_TTL
...
- UDP port allocation now falls back to claim_port_reuse() (SO_REUSEADDR)
- SO_REUSEADDR get/set added to both UDP and TCP schemes
- SO_BROADCAST getter added to UDP (always returns 1)
- IP_TTL getter/setter added to UDP (get/set hop_limit)
- TCP: SO_REUSEADDR get/set added for API completeness
- All new options return known values for application compatibility

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

stp: integrate 802.1D Spanning Tree Protocol into BridgeDevice
...
Adds loop prevention to Ethernet bridges:
- BridgeDevice gains stp: Option<StpState> field
- enable_stp(priority, mac) method initializes STP per-bridge
- BPDU frames (dst 01:80:c2:00:00:00) intercepted in recv(),
processed locally, never forwarded
- STP hello timer sends periodic BPDUs on all ports (root bridge)
- flood() skips STP-blocked ports
- build_bpdu() made public for bridge integration
- stp module declared in link/mod.rs
The recv() flow now: age MACs → check STP hello timer →
poll ports → detect BPDU (absorb) → normal frame (learn + forward).

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.
