Performance: event-driven stdout pump (no polling thread per socket, no 200ms
coalescing stall), keystrokes written immediately, blocking SSH reads, bounded
deque queue with batch drain, incremental UTF-8 decode, buffered session log,
non-blocking session teardown, shorter login/settle waits, xterm WebGL renderer
and idle-time direct writes. Zero-latency fake device: echo p50 11ms -> 2.3ms,
command RTT 219ms -> 20ms, bulk output 2.1 -> 8.3 MB/s.
Audit: track the device's own input row server-side (webcrt_cmd_audit) and
resolve each Enter from the echoed line feed, so Tab, backspace, cursor-key
edits, history recall, paste, Ctrl-C and pagers record what actually ran.
Password lines are redacted; pending Enters are flushed on close.
Hop: stop closing the hop session when the target prints the same prompt as the
hop (system-view); recognise the Huawei "closed by the remote host" message.
Generic NEs that show a network prompt now get the network key map.
Adds bench_webcrt.py, fake_ssh_device.py and e2e_webcrt_input_scenarios.py.

Fix bare Enter re-audits, Tab expansion lag, and history mid-line edits by preferring the xterm/device row at Enter and rejecting empty-prompt snapshots.

Audit every completed stdin line per flush, keep a list of audit_line hints from the router, restore prompt enrichment and stdout fallback, and record actual bytes when hints disagree with what was sent.

Only audit interactive commands from frontend audit_line with a CLI prompt prefix; skip prompt-sync Enter and device error echoes; join wrapped xterm rows for long commands.

xterm and keydown can both emit carriage return for one keypress; skip duplicate Enter frames on the client and collapse identical audits within 450ms on the server.

Do not reuse the previous command when the operator presses Enter on a blank prompt; validate prompt-only rows on both frontend and backend.

PTY stdout/stdin carry backspace and edit noise during typing; record only the final row the operator sees when pressing Enter.

ZTE tab redraws the input line via carriage return; parse the last prompt line from PTY stdout on Enter instead of stdin keystrokes. Also remove remaining ?? in AuditPage.

On Enter, send audit_line from the terminal row so tab completion and edits match what the operator executed; keep the device prompt prefix in audit logs.

Make session lifecycle and typed CLI lines searchable in audit_log with password redaction, and surface summaries plus device filters in the ops UI.

Skip Huawei special_login_handler under interactive WebCRT, harden stelnet host-key auth, and echo hop/login progress into the terminal during connect.
