Replace the flat message list on the session detail page with a chat-bubble conversation view inspired by Spotlight's AI Transcription. - User messages right-aligned in blue bubbles, assistant messages left-aligned with border - Tool calls rendered as collapsible <details> blocks with tool name badges inside assistant bubbles - Reasoning blocks collapsed by default with purple badges - Metadata below each bubble: agent/model ID, timestamp, token estimate - Client-side search/filter with debounced text matching, hit counter, and accent highlight ring on matches - Dark mode support with readable contrast overrides for user bubbles - Content truncation: 2000 chars for text, 1000 for tool/reasoning (collapsed), tool output scrollable at 300px max-height
