vh cfee89ac1c refactor(tui): streaming + turn headers + Thinking pane + picker fix (v0.6.0)
Operator-driven big-batch polish + restructure:

## 1. Streaming text — no more per-token RichLog spam

Pre-v0.6.0, every Text SSE delta wrote its own RichLog line, so
"Let me read the..." became 4+ separate lines (a Worldtree-style
sentence-by-sentence reveal that read as broken). v0.6.0 adds a
`#current-text` Static docked above the prompt; TuiPresenterState
buffers Text deltas in `text_buffer` and updates the Static in
place. On terminal event the Static clears and the transcript
gets:
  - raw=False: post-Done Markdown body + Rule separator
  - raw=True:  accumulated plain text

The Static collapses to height=0 when empty so the prompt sits at
the column bottom unchanged.

## 2. Turn-ID headers across every pane

`_stream_turn_worker` writes a `Rule(title="turn N")` to all four
log panes (transcript, tools, debug, thinking) on the first event
of each new turn. Operators can now visually correlate "what
happened in Tools during turn 42" by section markers in matching
positions across panes.

## 3. New Thinking TabPane (Ctrl+3)

Closed thinking runs now route to `#thinking-log` (a dedicated
TabPane) instead of `#debug-log`. Each closed run writes three
entries:
  - Rule(title="turn N · thinking #K start")
  - Markdown(thinking_content)
  - Rule(title="turn N · thinking #K end")

Model reasoning often has lists/code/structure — rendering as
Markdown (instead of the previous "· thinking: ..." prefix line)
makes it scannable. The `thinking_run_index` counter scopes per
turn so multi-thinking-run turns get distinct markers.

`thinking-current` Static (live per-delta preview) stays in the
right column above TabbedContent (unchanged from v0.5.0) — live
visibility persists across tab switches.

## 4. Agent picker — multi-line items, full description visible

Pre-v0.6.0 the picker rendered each agent as a single Label with
"{id} · {name} — {description}", which truncated descriptions
visually. v0.6.0 uses two Static children per ListItem:
  - bold Aurora bright-blue line: "{agent_id} · {name}"
  - wrapped Sea dark-60 line(s): full description

ListItems are auto-height so long descriptions wrap as needed.
Highlighted (--highlight) row uses Sea dark-30 background instead
of Aurora blue (which the operator flagged as ugly).

## 5. Kill residual blue chrome

The user's "background is still blue" report traced to the prompt
Input's focused border, which I'd set to $primary (Aurora blue).
Switched to $au-bright-cyan (#42dcd1) — focus highlight is now
cyan, consistent with the operator's-voice accent throughout the
TUI. Also added explicit overrides for ContentTabs strip
background + active-tab underline color → Australis cyan.

## 6. Surfaced emotion-appraisal request to worldtree-dev

User asked for emotion-appraisal telemetry, but no SSE event for
this exists in the spec — persona/Vili affect lives in persona.log
(file-tail, blocked on remote-Worldtree topology) and per-character
state (poll endpoint, not per-turn). Posted an althing thread
proposing two shapes (worker_phase payload extension OR new
affect_update event type) and routing the decision to their team.
A 4th `Emotion` TabPane plugs in trivially when a wire event lands.
Low-priority / quality-of-life framing — not blocking ship.

## Contract amendment

docs/contracts/issues/13.contract.md amended in-place: INV-019
extended to 3 TabPanes; new INV-021 (Text → current_text Static),
INV-022 (thinking closed runs → thinking_log with Markdown +
start/end Rules), INV-023 (turn-ID headers across all panes),
INV-024 (thinking-current Static stays in right column with
"thinking… " prefix per v0.5.1 polish). INV-020 (render-exception
fallback routing) updated for Thinking → thinking_log. Drift-check
clean.

## Tests

241 GREEN (down from 244 in test count — 5 routing tests rewritten
for the new shape, replacing the v0.5.0 thinking-in-debug-log
assertions with the v0.6.0 thinking-log-as-Markdown shape; net
test coverage equivalent). ruff clean.

Live smoke against personal Worldtree's mimir confirmed:
  - transcript: 27 lines (turn header + user echo + done +
    markdown body, NO per-token spam)
  - thinking_log: 19 lines (turn header + 2x thinking start/end
    Rule sections with Markdown bodies)
  - current_text cleared post-Done

Minor bump (v0.5.1 → v0.6.0) per SemVer etiquette: visible routing
+ new pane = operator-observable surface change.
