Navi Code: render planning as a progress line + plan card, not raw events ...

planning_status and plan_ready events were unhandled in the TUI chat model and
the raw CLI renderer, so they fell through to raw debug output (TUI:
"plan_ready: {...}" status lines; raw CLI: "[event: plan_ready] {msg}").

TUI:
- New renderers/planning.py: PlanningStatusRenderer renders a "⚙ Planning ·
  <label>" line (info color; dim + "(subagent)" prefix for subagent planning);
  PlanReadyRenderer renders the plan as a Panel wrapping themed Markdown, titled
  "Plan" with an accent border ("subagent plan" + dim border for subagents).
- Registered both in default_registry().
- chat_model handles the events: non-subagent planning_status rolls in place
  (Analysis → Execution plan → Plan review share one line instead of stacking);
  plan_ready consumes the pending planning line and appends the plan card;
  subagent planning is appended as its own dim line/card so it does not bleed
  into the parent turn's indicator (matching the webclient).
- chat_panel._refresh maps the new kinds to the registry.

Raw CLI (render.py): planning_status prints "[planning] <label>"; plan_ready
prints a "[plan] … [/plan]" block with the plan text.

Tests: renderer accepts/render (label, subagent prefix, plan title/content);
chat_model rolling-in-place, plan_ready consumes indicator, subagent separation.

fix(ws): include session_id/profile_id in session_sync, guard renderer ...

The server sent {"type": "session_sync"} without session_id/profile_id,
crashing the terminal client (render.py did None[:8]). Add the fields to
both session_sync sends and guard the renderer against a missing id.

Navi Code: Phase 2 — CLI terminal client, tests, docs ...

- Add clients/terminal package: config, state, REST API wrappers, WebSocket
  client, renderer, and click-based interactive CLI.
- Wire navi-code console script via pyproject.toml.
- Add unit and WebSocket integration tests for the terminal client.
- Update docs/profiles.md, docs/config.md, README.md with navi_code profile
  and default-profile instructions.
- Add docs/navi_code.md setup guide and docs/navi_code_cli.md usage reference.
- Fix lint in new test files and test_auth_disabled.py.

Tested: 459 passed, 1 skipped (excluded unrelated websocket test).
