docs(contract): amend issue #13 INV-024 for v0.6.1 thinking-current relocation

Three operator-flagged issues:

## 1. "Background is still blue" — Header sub-widgets + scrollbar

Two surviving blue sources after v0.6.0:

- **Header sub-widgets** (HeaderIcon, HeaderTitle, HeaderClock) each
  carry their own `$primary` tint that the parent
  `Header { background }` rule alone doesn't override. Sub-selectors
  added: `Header, HeaderIcon, HeaderTitle, HeaderClock { background:
  $surface; color: $au-bright-blue; }`.
- **Scrollbar gutter** uses Textual's `$primary-tint` (#32436a) by
  default. Per-widget scrollbar overrides: `ListView` (picker) and
  `RichLog` (every pane) get explicit Sea darks for gutter + thumb.

Live verification: both AgentPickerApp and RatatoskrApp now render
ZERO instances of `#6388d8` (Aurora blue) or `#32436a` (its dark
derivative) in the export-screenshot SVG.

## 2. "Picker is bright cyan with unreadable text" — ListView focus

Textual's default `ListView:focus > ListItem.--highlight { background:
$primary }` was overriding my v0.6.0 `#agent-list > ListItem.--highlight
{ background: $au-dark-30 }` because `:focus` carries higher
specificity. The highlighted item was rendering with Aurora-blue
background + bright-blue text = unreadable.

Fix: both selectors targeted explicitly with sufficient specificity:
`ListView > ListItem.--highlight, ListView:focus > ListItem.--highlight
{ background: $au-dark-30 }`. Description text bumped to Sea bright-70
for better contrast against the dark-30 highlight.

## 3. "Streaming everywhere, should just stream in line"

User flagged the disconnect: live thinking rendered above the
TabbedContent in the right-column header, then on closure the content
"moved" to thinking-log inside the Thinking pane. Read as jarring
discontinuity.

Fix: `thinking-current` Static moved INTO the Thinking TabPane (docked
bottom), below `thinking-log`. Both surfaces co-located now — live
streaming + closed runs share the same pane. Operator switches to
Ctrl+3 (Thinking) to see chronological closed runs ABOVE + live
streaming line BELOW. Same pattern as the transcript: closed history
+ inline streaming tail.

Trade-off: live thinking is now visible only when on the Thinking
tab. Pre-v0.6.1 it was always visible above the tabs. The user
explicitly prefers the co-located shape; this is the right call.

## Contract amendment

docs/contracts/issues/13.contract.md INV-024 amended: thinking-current
now docks bottom of the Thinking TabPane (was right-column header).
v0.6.0 layout-spec snapshot updated to reflect the new shape. Drift-
check clean.

## Tests + smoke

241/241 GREEN; ruff clean. Live smoke against personal Worldtree
confirmed:
- thinking-current AND thinking-log both inside thinking-tab.walk_children().
- Post-Done state: 23 closed-run lines in thinking-log, thinking-current
  cleared to empty.
- Picker exports zero blue rects; main App exports zero blue rects.

Patch bump (v0.6.0 → v0.6.1): purely cosmetic + layout adjustment
within the existing pane structure; no public-API change.

 - **INV-021** *(new v0.6.0)*: `Text` events do NOT route to `log` per-delta. They accumulate into `TuiPresenterState.text_buffer` and update a single `current_text` Static (docked above the prompt). On terminal event (`Done`/`Error`/`Cancelled`), `current_text` is cleared and (raw mode) accumulated text or (non-raw) post-Done `Markdown(response)` is written to `log`. The pre-v0.6.0 per-token RichLog spam is retired.
 - **INV-022** *(new v0.6.0)*: Closed thinking runs route to `thinking_log`, NOT `debug_log`. Each closed run writes three entries: `Rule(title=f"turn N · thinking #K start")`, `Markdown(content)`, `Rule(title=f"turn N · thinking #K end")` — the model's chain-of-thought is presented as rendered Markdown (model reasoning often has lists / code / structure) wrapped in operator-visible start/end markers. `thinking_run_index` increments per-run within a turn.
 - **INV-023** *(new v0.6.0)*: Turn-ID header `Rule(title=f"turn N")` is written to all four log panes (`log`, `tools_log`, `debug_log`, `thinking_log`) by `_stream_turn_worker` on the first event of each turn — enables cross-pane visual correlation during multi-turn debugging.
-- **INV-024** *(new v0.6.0)*: `thinking-current` Static remains in the right column (above TabbedContent) per INV-017 — live per-delta thinking visibility persists across tab switches. Prefix `thinking… ` self-identifies the widget contents.
+- **INV-024** *(amended v0.6.1)*: `thinking-current` Static lives INSIDE the Thinking TabPane (docked bottom, below `thinking-log`) — co-located with closed thinking runs so the operator sees streaming + history in one pane. Pre-v0.6.1 it sat above the TabbedContent (right-column header) which created a top/bottom discontinuity; the co-located shape resolves that. Trade-off: live thinking is now visible only when the Thinking tab is active (Ctrl+3). Prefix `thinking… ` self-identifies the widget contents.
