Captures the ReAct streaming contract bug + WS event whitelist governance
from PR #13's review fixes. Three intertwined runtime issues documented:

1. P0: final_answer double-accumulated token content (logic_error)
2. P0: _VALID_TEAM_EVENT_TYPES whitelist missing 3 new streaming event types
3. P2: except (RuntimeError, TimeoutError, ConnectionError) too narrow for
   LLMProviderError/ConfigValidationError in async generator

Adds ReAct Streaming Contract entry to CONCEPTS.md — defines the protocol
execute_stream() yields (token events with incremental content, then one
final_answer event with the concatenated full text). Consumers must pick
one accumulation strategy, cannot mix both without doubled output.

U1 ThinkingBlock: streaming cursor + auto-collapse to summary bar
U2 StickyModeHeader: new component replacing ExpertTeamView + BoardStatusView
U3 Backend _phase_executor: execute_stream() with token/thinking/final_answer forwarding
U4 Frontend chatStream: expert_result_chunk/team_synthesis_chunk token accumulation
U5 AssistantText: routing tag hover fade-in
U6 UserBubble: hover actions (copy/delete/refill)
U7 CalendarGrid: token-based color redesign

Review fixes (ce-code-review):
- P0: _VALID_TEAM_EVENT_TYPES whitelist adds 3 new streaming event types
- P0: final_answer no longer double-accumulates token content
- P2: exception handling expanded to except Exception for LLMProviderError etc.

Simplification (ce-simplify-code):
- _synthesizer.py: O(n²) concat -> list+join, _concat_results extraction
- config_driven.py: 4 duplicate _handle_*_stream -> _wrap_sync_as_stream
- chatStream.ts: 5x [...messages].reverse().find() -> findLastMessage helper

Tests: pytest 13/13, vitest 126/127 (1 baseline), typecheck pass, ruff clean
