fix(tui): drop post-Done Markdown body re-render (v0.8.2)

Operator: "first turn double prints agent's turn."

Root cause: v0.8.1 wrote both the streamed Text lines AND the post-
Done `Markdown(event.response)` body into the transcript. Same
content rendered twice — once as plain streaming, once as a full
markdown re-render. The v0.8.1 commit message documented this as
"some duplication is acceptable" but the live UX read as a bug.

## Fix

Drop the post-Done `Rule + Markdown(response)` writes in non-raw
mode. The streamed text IS the response; whatever the model emitted
flows into the transcript line-by-line via coalesce-on-newline.
Markdown formatting (bold, lists, code blocks) renders as plain
text — a known regression from v0.8.1's polished output but the
right tradeoff vs the duplication bug.

## What this loses temporarily

Pre-v0.8.2 (after Done):
  [done] turn_id=... ───
  ─── (Rule separator) ───
  **Bold text** rendered bold, `code` highlighted, lists as bullets, etc.

v0.8.2 (after Done):
  [done] turn_id=... ───
  **Bold text** as plain asterisks, `code` as backticks, lists as plain dashes

## v0.9.0 plan

Restore markdown rendering via LIVE rendering during the stream
(not post-Done re-render). Replace `RichLog#transcript` with a
`VerticalScroll` container that mounts a fresh `Markdown` widget
per turn; Text deltas update the widget; markdown renders as
content arrives. No duplication, no snap, full formatting.
Operator-confirmed direction (2026-05-25 AskUserQuestion).

## Tests

287/287 GREEN; ruff clean. Two tests updated for the new shape:
- test_done_renders_markdown_after_label → renamed
  test_done_flushes_tail_and_writes_label; asserts NO Markdown, NO
  Rule (post-Done) in the writes.
- test_happy_text_done_renders_markdown → renamed
  test_happy_text_done_no_double_print; asserts NO Markdown in the
  spy.

Patch bump (v0.8.1 → v0.8.2): bug fix; no public API change.

+Workaround for Worldtree's ``GET /agents`` not returning consumer-defined

+
+If Worldtree later starts returning tier-3 agents in ``GET /agents``, this
+module's role narrows to redundant local cache; can be removed cleanly
+since the picker's dedup-by-agent-id keeps remote-wins behavior.
+
+Failure modes are lenient: missing file → empty index; corrupt JSON or

+foundational agents either way; the local-tier-3 surface degrades to
