v1.29.0

• appearance.firstFrame ("php" default, "window"): with "window"
  the Android activity draws its themed window at once instead of holding
  the launch screen until PHP's first frame, and builds the native modules
  right after that first draw; iOS skips the launch cover. For apps whose
  first PHP frame only paints the background it shows the same pixels
  sooner (Galaxy S10 cold start, Zé Chat: TTID 316 -> 230-237 ms median).
• Android: a module call made before the native modules exist is queued
  and replayed in order once they are built, instead of blocking the PHP
  thread (calls complete asynchronously anyway).
• PHP SDK: the prebuilt component pack lists every component source; a
  staged bundle (manifest.sha256 beside the pack) boots from that listing
  without walking src/ or reading and fingerprinting each component
  (S10: component discovery 33 -> 3 ms of the first frame). Development
  trees and hot reload bundles carry no pack and keep validating.
• Android: release bundles live in content-addressed directories, so PHP's
  opcache no longer stats the source of every include
  (opcache.validate_timestamps=0 outside debug builds, which hot reload in
  place).
• Android VirtualizedList: history prepended above the rows (also when a
  bounded window drops rows at its other end) restarts the prefetch ramp of
  that side only, like appended pages; the rows laid out on the other side
  stay bound instead of being recycled and bound again.
• Android cell binds: the pool key of a cell view is a property bit set
  (no sorting/joining strings), image request identity is the immutable
  request itself (no joined signature), and drag and tap-effect programs
  are parsed once per distinct source (PamParseCache; iOS: drag configs).
• Android: ActivityIndicator no longer inflates the theme's
  AnimatedVectorDrawable it immediately replaces (15-25 ms on the UI thread
  for each new spinner, e.g. a list's "loading older rows" cell).
