Replace the single aggregate thinking tile with per-turn thinking groups.
Instead of collecting all thinking messages into one flat array and
rendering a single ThinkingProcess before the last assistant message,
process session.messages in chronological order to produce interleaved
display items that naturally group consecutive thinking messages by turn.
Each turn now shows its own collapsible thinking tile placed inline
before its assistant response, with correct per-turn isActive state
and turnStartedAt from the matching run.
Also fixes a latent index-mismatch bug in getAssistantMessagePhase where
the visible-messages index was compared against the full session.messages
index, potentially hiding the Final badge when thinking messages existed.
Switched to ID-based comparison.

Wire message-reclassified sidecar events through the main process to
the renderer, where reclassified messages are filtered out of the main
transcript and collected into a collapsible ThinkingProcess component.
Main process changes:
- Route message-reclassified via dedicated onMessageReclassified callback
- Add applyMessageReclassified handler that sets messageKind and emits
the session event for the renderer
- Forward assistant-intent and reasoning-delta as turn-scoped events
Renderer changes:
- Split session.messages into visibleMessages and thinkingMessages
- Render ThinkingProcess above the last assistant message
- ThinkingProcess auto-expands during active turns, collapses on finish
- Update messagePhase to skip thinking-kind messages for final detection
Tests:
- 3 new sessionWorkspace tests for reclassification apply/dedup/ignore
- 2 new messagePhase tests for thinking-kind handling
- Updated runTurnPending test fixtures for new callback
