lightfirstandKKRainbow 7592951b80 fix(dataplane): route UDP by bound local endpoints (#2652) ...

Register one UDP flow at bind so sockets can receive from new peers
before their first send. Allocate and reserve ports within each instance
independently of TUN and Host sockets. Release the endpoint on close.
Search the ephemeral range once and preserve concurrent cursor progress.

Route local UDP fragments by the first fragment's bound endpoint. Buffer
earlier tails in a bounded shallow cache and forward original packets to
one recipient. Preserve cached ownership across binding changes, expire
idle entries, and clear state on address changes and runtime shutdown.
This avoids orphan fragments exhausting smoltcp's reassembly slots while
keeping original packet sizes for TUN and proxy consumers.

Randomize each new stack's seed to avoid replaying IP IDs on rebuild.
Document accepted residual collision-related UDP loss or downstream
delivery instead of adding fragment completion tracking.

Allow peer filters to return a batch, resuming each packet at the next
filter without repeating earlier filters. The single-packet path does
not allocate a batch queue. Keep ZCPacket and IpReassembler unchanged.

Cover endpoint ownership, ephemeral allocation, out-of-order fragments,
cache limits and expiry, binding changes, batch continuation, and large
UDP datagrams after more than 16 complete unrelated fragmented
datagrams.

Exercise two recreated sending stacks with controlled seeds to verify
that new fragments do not inherit an old downstream route.
