32ca6039a0 fix(lwip): reject invalid DHCP MTU option values 
Validate MTU from DHCP option 26 against RFC 2132 minimum (68 bytes)
before applying to netif->mtu, preventing rogue DHCP servers from
setting MTU to 0 or other dangerously low values that cause integer
wraparound in IPv4 fragmentation.

d244a37c12 feat(lwip): Add IPv6 static neighbor cache entry support 
Add esp_netif_add_static_neighbor() and esp_netif_remove_static_neighbor(),
gated by CONFIG_LWIP_ND6_SUPPORT_STATIC_ENTRIES. These API's let callers
install/remove permanent IPv6->MAC mappings that bypass Neighbor Discovery
(no NS/NA). The calls run in the TCP/IP context and wrap the underlying lwIP
nd6_add_static_neighbor()/nd6_remove_static_neighbor() functions.

62a28e250f feat(lwip): replace --wrap linker hacks with proper VFS registration on linux builds 
The Linux LWIP port was using --wrap linker flags to intercept read,
write, close, fcntl and select, routing socket FDs (>= LWIP_SOCKET_OFFSET)
to lwip_*() functions. This conflicted with the dlsym(RTLD_NEXT)
cooperative syscall interposition used by the new FreeRTOS Linux
simulator.

Replace the --wrap approach with esp_vfs_register_fd_range(), matching
how LWIP already integrates with VFS on bare-metal ESP32 targets.
The cooperative read()/write() wrappers in vfs_coop_syscalls.c check
VFS first, so LWIP FDs are dispatched to lwip_read() etc. before the
cooperative fallback path is reached.

22b75a18bc fix(lwip): Fix DHCP server potentially incomplete pbuf copy 
handle_dhcp: use pbuf_copy_partial for safe chain traversal

The manual two-segment copy loop was replaced with a single call
to pbuf_copy_partial(p, p_dhcps_msg, tlen, 0), which correctly
walks the entire pbuf chain regardless of segmentation.
A return-value check rejects truncated copies.
