🚣‍♀️ feat: Smooth Streaming Text Fade-In (#14757)
* 🚣‍♀️ feat: Smooth Streaming Text Fade-In

Adds a native FlowToken-style fade-in for streamed message text, with no
changes to the streaming data path: a per-block rehype plugin wraps newly
arrived words in one-shot CSS fade spans, using document-order character
offsets so already-visible text never re-animates, even when markdown
re-parsing restructures the tree. Words still inside their animation
window replay identical props so in-flight fades are never cut short.

- New Content/animate.tsx: word splitting (Intl.Segmenter for CJK),
  offset-based new-text classification, rehype plugin factory, and an
  AnimatedText component for plain-text reasoning content
- MarkdownBlocks: per-block plugin instance appended to the cached
  rehype plugins only while animating; block memoization untouched
  (bench asserts identical code-block render counts)
- Animation gated on isSubmitting && isLatestMessage and dropped at
  stream end, so settled messages render without wrapper spans
- Skips code, pre, math/KaTeX, artifacts, citations, and MCP UI subtrees
- Smooth streaming toggle (default on) under Settings → Chat → Messages;
  animation disabled under prefers-reduced-motion
- Extends the streaming bench with a fade variant (+9% render time in
  jsdom, 62/62 code-block renders) and adds unit tests for the plugin,
  classification, and AnimatedText

* 🛡️ fix: Harden Streaming Fade for Resume, Concurrency, and Reduced Motion

Addresses Codex review on the smooth streaming fade:

- Hydrated/resumed content becomes the animation baseline: a renderer whose
  first run already exceeds FADE_HYDRATION_THRESHOLD (reconnected stream,
  conversation switch) no longer re-fades the entire accumulated response
- Classification is now transactional under React 18 concurrency: runs are
  staged during render and published via commit() from a layout effect, so
  abandoned renders (interruption, StrictMode double-render) leave no trace
- prefers-reduced-motion now disables the rehype transform and AnimatedText
  in the render gate, not just the CSS animation, so reduced-motion users
  skip the span-wrapping work entirely

* 🌏 fix: Refine Fade Hydration Signal, Spaceless Scripts, Collapsed Reasoning

Second Codex review round on the smooth streaming fade:

- Hydration is now an explicit signal instead of a per-block length guess:
  Markdown captures whether substantial content already exists at the render
  where its animate gate flips on, and passes it to each block's plugin. New
  blocks mounting later in the stream always animate regardless of size, and
  resumed content becomes the baseline regardless of block sizes
- Word segmentation now covers all spaceless scripts (Thai, Lao, Tibetan,
  Myanmar, Khmer) in addition to CJK/Hangul, so continuously streamed text in
  those scripts keeps fading instead of freezing after the first window
- Reasoning text no longer runs the word transform while the thinking panel
  is collapsed; expanding mid-stream starts from a hydrated baseline

* 🖱️ feat: Hide Streaming Cursors While Smooth Fade Is Active

The word fade itself signals streaming, so the trailing block cursor
(result-streaming) and the pulsing thinking dot (result-thinking) are
now suppressed whenever the smooth streaming fade is enabled. Both
return when the setting is off or the device prefers reduced motion.
Extracts the shared gate into a useSmoothStreaming hook consumed by
Markdown, Reasoning, TextPart, DisplayMessage, EmptyText, and the
legacy loading fallback.

*  test: Pin Cursor Assertions to Fade-Off State

The pulsing thinking cursor now only renders while the smooth streaming
fade is off, so the tests asserting it set the toggle off first (at file
level where earlier renders would cache the atom's first read).

* 💫 feat: Restore Start-of-Run Dot With Fade-Matched Treatment

The trailing streaming cursor stays hidden while the fade is active (the
fade itself signals text arriving), but the pre-first-token dot returns:
nothing else tells the user the run started before any text exists.

Restyled to match the word fade rather than the classic size throb — it
fades in on the same 250ms ease-out curve, then breathes on opacity, so
"run starting" and "text arriving" read as one system. Applied only when
the fade is active; with the setting off or reduced motion preferred the
dot keeps its original pulseSize behavior, so the cursor assertions in
the existing suites hold unchanged.
