refactor(tui): content-only main pane + Debug tab + dark chrome (v0.5.0)

Two operator-driven changes off v0.4.1:

1. **Main pane is content-only.** Pre-v0.5.0 the transcript mixed
   assistant text with telemetry (Thinking closed runs, WorkerPhase,
   TextBoundary) — only tool events were factored out per #13. The
   transcript now receives ONLY: user-prompt echo, assistant Text
   deltas, [done]/[error]/[cancelled] terminal labels, and the
   post-Done Markdown render. All telemetry routes to a new Debug
   tab in the right column.

2. **Chrome no longer blue.** Textual's default Header / Footer /
   active-tab styling tints with `$primary` (Aurora blue under
   Australis), which read as garish on dark terminals. Header,
   Footer, and the TabbedContent tab strip get explicit
   `background: $surface` (Sea bright-black #373b46) so the chrome
   sits cool and unobtrusive against the Ice black background.

## Layout reshape

```
LEFT COLUMN (content only):           RIGHT COLUMN (telemetry):
  transcript (RichLog, 1fr)             thinking-current (Static, dock top)
  prompt (Input, dock bottom)           TabbedContent:
                                          Tools  (tool_start, tool_result)
                                          Debug  (thinking, worker_phase,
                                                  text_boundary)
```

The thinking-current live-preview Static moves from left → right
column so the left column is genuinely content-only. Live thinking
visibility now persists across tab switches (it docks above the
TabbedContent, not inside any tab).

## Presenter routing (TuiPresenterState.render)

Signature widens with `debug_log: RichLog`. Routing matrix:

  Text                       → log (transcript)
  Done / Error / Cancelled   → log (transcript) [terminal labels]
  ToolStart / ToolResult     → tools_log (Tools tab)
  Thinking (closed run)      → debug_log (Debug tab)
  WorkerPhase                → debug_log (Debug tab)
  TextBoundary               → debug_log (Debug tab)
  Thinking (per-delta)       → thinking_widget (live preview)

INV-009 render-exception fallback preserves routing per event class
(new INV-020) — ToolStart/Result falls back to tools_log;
Thinking/WorkerPhase/TextBoundary to debug_log; everything else to log.

## Keybindings

- Ctrl+1 → Tools tab (existing, unchanged)
- Ctrl+2 → Debug tab (NEW)

`pane-name` footer widget updates dynamically as the operator
switches tabs ("Tools" ↔ "Debug"). This was previously deferred to
"the multi-tab issue" per the Volva contract-review amendment;
multi-tab now exists, so the dynamic update lands here.

## Contract amendments

docs/contracts/issues/13.contract.md amended in-place:
- INV-015 amended: transcript is content-only; telemetry routes to
  debug_log. Old routing (telemetry in transcript) retired under the
  no-backwards-compat rule.
- INV-017 amended: thinking-current docks to right column (was left).
- INV-019 new: two TabPanes (Tools + Debug), Ctrl+1/Ctrl+2 bindings,
  dynamic pane-name update.
- INV-020 new: render-exception fallback preserves per-event-class
  routing.
- Layout-spec snapshot ASCII diagram updated.

Drift-check clean.

## Tests

239/239 GREEN (+3 new: debug_tab_exists, ctrl_2_activates_debug_tab,
pane_name_updates_on_tab_switch). 6 existing tests adjusted for the
new routing (test_thinking_closes_one_debuglog_entry,
test_multiple_thinking_runs_each_get_debuglog_entry,
test_render_exception_fallback,
test_cancelled_mid_thinking_closes,
test_worker_phase_demoted_to_debug_log,
test_left_column_content_only). ruff clean.

Live smoke against personal Worldtree: mimir KB-search turn
populated tools_log with 11 lines of tool events (search_library +
read_note); debug_log with 20 lines of worker_phase + thinking
content; transcript stayed content-only with `❯ user-prompt`
(Aurora bright-cyan) + assistant text deltas. Routing matrix
holds end-to-end. (Diagnostic note: RichLog.lines is the rendered-
output buffer; inactive TabPane content shows lines=0 until the
tab activates and renders. Internal write store is correct — this
is a Textual rendering quirk, not a routing bug.)

Minor bump (v0.4.1 → v0.5.0) per SemVer etiquette: visible routing
surface change for operators; transcript and Debug tab contents
look different from yesterday's v0.4.1.

- **INV-013**: Layout is `Horizontal` two-column. Left column width = 2fr; right column width = 1fr.
- **INV-014**: `ToolStart` / `ToolResult` events route to `tools_log` (Tools pane), never to `log` (transcript).
- **INV-015**: Every other event type (`Text`, `Thinking`, `WorkerPhase`, `TextBoundary`, `Done`, `Error`, `Cancelled`) keeps its issue-#12 routing target (`log` for chronological entries; `thinking_widget` for live deltas).
- **INV-016**: Input retains keyboard focus across `Ctrl+1` tab switch.
- **INV-017**: `thinking-current` Static docks to the top of the **left column**, not the whole App — TabbedContent's vertical extent on the right is independent of thinking-runs starting/stopping.
- **INV-015** *(amended v0.5.0)*: The transcript (`log`) is **content-only** — receives `Text`, `Done` (label + Markdown body + Rule), `Error`, `Cancelled`, and the user-prompt echo (` <content>`). **All telemetry events (`Thinking` closed runs, `WorkerPhase`, `TextBoundary`) route to `debug_log` (Debug pane), NOT `log`.** Live thinking deltas continue to update `thinking_widget` per-delta. The pre-v0.5.0 shape (telemetry mixed into transcript) is retired under the project's no-backwards-compat rule.

- **INV-017** *(amended v0.5.0)*: `thinking-current` Static docks to the top of the **right column** (above `TabbedContent`), not the left column. Live thinking visibility persists across tab switches. v0.5.0 moves it from left → right so the left column is genuinely content-only.
- **INV-018**: CLI mode (`ratatoskr.cli._amain`) is unaffected. CLI keeps inline `· tool_start: …` / `· tool_result: …` rendering on stderr per issue #12 INV-005.
- **INV-019** *(new v0.5.0)*: Two TabPanes in the right column: `Tools` (id `tools-tab`, contains `#tools-log`) + `Debug` (id `debug-tab`, contains `#debug-log`). Ctrl+1 activates Tools; Ctrl+2 activates Debug. `pane-name` Static reflects the active tab name dynamically.
- **INV-020** *(new v0.5.0)*: Render-exception fallback (INV-009) preserves routing per event class: `ToolStart` / `ToolResult` fallback writes to `tools_log`; `WorkerPhase` / `Thinking` / `TextBoundary` fallback writes to `debug_log`; everything else falls back to `log`.
## TESTS (additions / changes to test_tui.py)
@@ -185,21 +187,28 @@ Existing tests that need adjustment (NOT rewrite):
All error routing from issues #4 / #6 / #7 / #12 stays verbatim. The tools_log routing change is internal to the presenter; error paths (`SseConnectFailed`, `SseConnectionDropped`, `MalformedSseId`, `MalformedSseData`, `TurnIdFlip`) all write their labeled lines to `log` (the main transcript). Reason: errors are turn-terminal and need to be visible in the operator's primary attention surface; routing them to the Tools pane would hide them behind a tab switch.

`Tools` (tool events) and `Debug` (thinking closed runs + worker_phase +
text_boundary).
