Navi Code TUI: show request duration (live timer + chat metadata) ...

Live elapsed timer next to the activity indicator (ticks once per second
during a turn, format 2m 16s), driven by the same stream_start/stream_end
hooks as the activity indicator — so it spans the whole turn (all LLM calls,
tool calls, planning, sub-agent steps). On stream_end it syncs to the
backend's authoritative elapsed_seconds before freezing; on stream_stopped/
error/disconnect it freezes at the locally-measured value.

On stream_end the model also appends a turn_meta ChatItem rendered as a dim
"⏱ 2m 16s" line below the answer — the total time the agent spent on the
user's request. The value comes from stream_end.elapsed_seconds, already
measured by the backend over the whole turn, so the TUI needs no timer for
accuracy. stream_stopped/error do not get a metadata line (only completed
requests).

Shared format_duration(): None -> "—", <60s -> "16s", <3600 -> "2m 16s",
>=3600 -> "1h 2m".

Navi Code TUI: context-window fill gauge in the status bar ...

Add a ContextFill widget to the bottom StatusBar showing how full the LLM
context window is (absolute tokens + percent), colored by fill level:
dim < 70%, warning 70-89%, error >= 90%. Updates from stream_end and
compression_started/context_compressed events; seeded from get_session on
resume so the gauge isn't blank pre-turn. None from the backend keeps the
last known value.

Fix: name the widget attribute _ctx_fill, not _context — _context shadows
MessagePump._context (the internal context manager Textual wraps around
message processing) and hangs the app's message pump at mount time.

Polish: drop the "ctx " prefix (shows 12.0k/32.0k · 38%) and add a 1-char
margin between the activity indicator and the gauge.

tui: load session message history into the chat panel on resume ...

Resuming or switching a session showed a blank chat — the past conversation
was never replayed. GET /sessions/{id} already returns the messages; the TUI
just ignored them.

- ChatModel.load_history maps persisted Message dicts back to the same
  ChatItems the live stream produces (user/assistant text, thinking, tool
  started/result, plan), skipping is_display=False (context-only user,
  summaries, compression events) so only what the user would have seen
  live is rebuilt.
- ChatPanel.load_history wraps it (clears the render cache + refresh).
- attach_session loads the messages from get_session, so resume/switch
  replays the history before the cwd/Connected banners.

tui: activity indicator in a bottom status bar + 1-line input ...

Add an animated "agent is working" indicator so a silent gap (long-running
tool, the pause before the first token, sub-agent reasoning) reads as
"alive" rather than "hung": a braille spinner + phase label that runs on
its own timer, independent of the WebSocket event flow.

- New ActivityIndicator widget (rotating spinner + phase label, colored
  status_online), started/stopped from tui_app WS phase transitions
  (thinking / responding / planning / running <tool>) and stopped on
  stream_end/stopped/error and on connection drop.
- New StatusBar bottom line replaces Textual's Footer: indicator on the
  left, dim key-combo summary on the right. One line instead of the menu;
  the key bindings themselves stay on the App so the keys still work.
- Input box: TextArea min-height 3 -> 1, so the prompt is one line by
  default (auto-resize + max-height 12 unchanged).

tui: add --resume <session_id> and print resume hint on TUI close ...

Closing Navi Code now tells the user the session id and the exact command to
continue it, so a session is one re-run away instead of lost to state lookup.

- cli.py: add --resume <session_id> (mutex with --new-session). Raw and TUI
  paths resolve the given id via api.get_session; a bad id is a hard error,
  not a silent new session. After app.run() returns and the terminal is
  restored, print "Session <id>" / "Resume with: navi-code --resume <id>"
  when a session is attached.
- tui_app._resolve_session: make the explicit-id branch strict — a failed
  get_session surfaces an error event and returns None instead of falling
  through to creating a new session (a --resume typo used to silently start
  a fresh session). Saved-state resume stays lenient.
- tests: resume-flag resolve/bad-id/mutex + hint format; tui strict-on-bad
  explicit id and explicit-id resume.

tui: show the currently-served model in the status panel ...

The status panel's Model line was fed the global ollama_default_model, not the
session/profile model, and the server never told the client which model
actually served a call. Now:

- Backends stamp the resolved model onto LLMChunk (first chunk) / LLMResponse.
  The fallback backend reports the model that survived its server+model
  priority list (may differ from the profile's first choice).
- New ModelInfo event ({"type":"model_info","model":...}) emitted once per
  turn from agent._consume_stream, re-emitted only when the model changes
  across iterations. Additive WS event — old clients ignore it.
- TUI: attach_session/switch fetch the profile's configured model (first of
  profile.model) via api.get_profile_model so the panel shows a value before
  the first request; model_info then refines it to the actually-served model.
  Not forwarded to the chat panel. raw CLI prints "[model] ...".

Navi Code TUI: fix input box layout, command palette duplicate IDs, status renderer, and WS input loop ...

- clients/terminal/tui/widgets/input_box.py: switch Horizontal to Vertical with width: 100% for Input so it renders and accepts input in real terminals; add refresh on Input.Changed.
- clients/terminal/tui/screens/command_palette.py: remove fixed ListItem IDs to avoid DuplicateIds on fast filter.
- clients/terminal/tui/chat_model.py + renderers/status.py + widgets/chat_panel.py: render backend status events as dim system messages instead of raw dicts.
- clients/terminal/tui/ws_bridge.py: start NaviWebSocketClient.input_loop so enqueued user messages are actually sent to the backend.
- clients/terminal/tui/tui_app.py: focus InputBox synchronously in on_mount so typing works immediately.
- tests/clients/test_tui_app.py: regression test for visible input text.
