Alem Tuzlak b941298cc1 fix(showcase/aimock): chain tool-rendering follow-ups via toolCallId so multi-pill sessions work ...

The tool-rendering, frontend-tools-async, and hitl-in-app fixtures all gated
their first-leg (tool-emitting) vs. follow-up (narration) responses on
`hasToolResult: false/true` and/or `turnIndex`. Those constraints count the
*entire* thread, so once a user clicked a tool-using pill the thread already
contained tool messages and assistant turns and subsequent pill clicks fell
through to the wrong branch — d20 dropped from 5 rolls to 3, Chain tools
emitted no cards, query_notes returned narration without the Notes DB card,
and the second HITL pill never raised an approval dialog.

Re-key every follow-up fixture on the prior step's `toolCallId` (the matcher
checks `messages[last].tool_call_id`), drop the global `hasToolResult` gates
from the tool-emitting fixtures, and reorder so the toolCallId-specific
fixtures come first under first-match-wins. The d20 chain becomes a linear
toolCallId graph (`call_tr_d20_seq_001` → `_002` → … → `_005`), Chain tools
gets disambiguators for each of its three parallel tool_call_ids, and
Weather/AAPL/query_notes/HITL approve+reject branches all gate on the
specific request_user_approval / get_weather / query_notes / get_stock_price
id that landed last. userMessage matchers are unchanged.

Adds Playwright multi-pill regression tests to the four affected demos that
click every pill sequentially in one thread and assert the full card counts:
- tool-rendering-default-catchall: Find flights → 5 d20 rolls (with 20 last)
- tool-rendering-custom-catchall: 1 flights + 5 d20 + 3 chain = 9 cards
- frontend-tools-async: 3 NOTES DB cards with the right keyword per pill
- hitl-in-app: refund approve then escalate, each with its own dialog
