Modified Files:
src/ssh/test/test_chan.c test_conn.c test_transport.c
Log Message:
Add tests for full public API and function coverage

18 new tests across 3 files covering all previously-untested
DSSH_PUBLIC functions and the last 4 uncovered internal functions:

test_chan.c:
- params_set_max_window: dssh_chan_params_set_max_window unit test

test_transport.c:
- kex/set_ctx: dssh_kex_set_ctx + NULL/unknown/TOOLATE guards
- gather/set, gather/toolate: dssh_transport_set_tx_gather
- gather/roundtrip: full handshake through scatter/gather TX path
- rxline/from_rx_handshake: handshake with NULL rxline callback,
exercises the rxline_from_rx fallback

test_conn.c:
- zc/open_client: client-side dssh_chan_zc_open roundtrip
(also exercises dssh_chan_zc_getbuf + dssh_chan_zc_send)
- zc/cancel: dssh_chan_zc_cancel after getbuf
- null/zc_open: NULL guards for all ZC functions
- event/session_set_cb + toolate: dssh_session_set_event_cb
- event/chan_set_cb: dssh_chan_set_event_cb
- event/session_set_max + toolate: dssh_session_set_max_events
- event/chan_set_max: dssh_chan_set_max_events
- pty/get_pty: dssh_chan_get_pty with PTY and non-PTY channels
- env/roundtrip: env vars through accept_parse_env/parse_env_data

Result: 0 missed functions in all 4 core files, 75% branch coverage.
