isaac 562de27c30 InstantPage V2: AI streaming animation for rich-data bubbles ... Spec, plan, and full implementation of the AI-message streaming animation in ChatMessageRichDataBubbleContentNode. Extracts TextRevealController into a shared StreamingTextReveal submodule; precomputes per-character rects in V2 layout (RTL-safe, glyph-ink bounds); splits InstantPageV2TextView into render container + render view with a reveal mask layer; implements mask + snippet pop-in reveal; adds a per-text-view reveal cost map + applyReveal extension; switches reveal cost to a width-based unit; sizes / clips the bubble to the revealed prefix during streaming; aligns the Thinking… header with TextBubble; floors table cell reveal cost at cell frame width; includes layout closing pad in revealedContentSize; documents the non-obvious invariants in CLAUDE.md.		2026-05-20 00:34:07 +08:00
