evgeny 38c9f229bc stcp: ed25519 pubkey exchange in handshake, fix instance destroy segfault, fix chat_tcp_test
- u_async.c: process immediate_queue BEFORE epoll_wait in uasync_poll
- stcp_link.c: defensive NULL etcp_conn/etcp_link in stcp_link_close
- utun_instance.c: move stcp_server_list_destroy_all to Phase J (before ETCP),
  add deferred drain in both Phase J and L
- stcp.h/c: STCP_HS_ENC_CLIENT 6→38, STCP_HS_ENC_SERVER 7→39,
  exchange ed25519_pubkey in both handshake directions
- etcp_connections.c: copy peer_ed25519 from STCP to ETCP_CONN in
  etcp_link_enter_ready_tcp; guard link->etcp in tcp_link_close_cb
- chat_sync.c: fix lk->conn NULL dereference for TCP links
- test_stcp.c: update stcp_server_create/stcp_client_connect callsites
- tools/chat_tcp_test: change transport udp→tcp

evgeny d773f1724a refactor: STCP connections as ETCP links (is_tcp)
- Add is_tcp, tcp_link, tcp_reconnect_* fields to ETCP_LINK
- Remove transport_link from ETCP_CONN, add tcp_link_count
- stcp_link: replace embedded etcp_conn with pointer; add etcp_link backpointer
- stcp_link: link_rx_cb routes ETCP data to etcp_conn_input
- stcp_link: call on_close_cb in close
- New TCP functions: etcp_link_enter_ready_tcp, etcp_tcp_link_start_connect,
  etcp_tcp_link_start_reconnect, tcp_link_close_cb, etcp_tcp_send
- etcp_link_new: handle NULL conn for TCP links; skip enter_init for TCP
- etcp_link_close: close stcp_link for TCP
- etcp_encrypt_send: redirect TCP to etcp_tcp_send (skips AES-CCM)
- tcp_server_on_link: create ETCP_LINK(is_tcp=1) + enter_ready_tcp
- etcp_connect: TCP addrs -> etcp_tcp_link_start_connect
- Remove ctx->tcp_link/tcp_ready
- test_stcp_traffic: find stcp_link via links->is_tcp instead of transport_link
- 66/68 tests pass; 2 STCP tests expected to fail (integration not complete)

Evgeny 22dd1b78c3 Add local_link_id exchange in ETCP handshake (0x02-0x05)
- Add etcp_find_free_local_link_id() function to allocate unique link IDs
- Modify etcp_link_new() to auto-assign local_link_id, fail if none available
- Update INIT_REQUEST (0x02/0x04) to send local_link_id after keepalive
- Update INIT_RESPONSE (0x03/0x05) to include local_link_id
- Parse remote_link_id from incoming handshake packets
- Update protocol documentation in doc/etcp_protocol.txt
- Add comprehensive unit test test_etcp_link_id.c

New packet format:
INIT_REQUEST:  [code][node_id(8)][mtu(2)][keepalive(2)][link_id(1)][pubkey(64)]
INIT_RESPONSE: [code][node_id(8)][mtu(2)][link_id(1)]
