* fix(app): restore character-paced streaming reveal
Restore the v0.8 character reveal model and remove the word-level fade implementation so streamed assistant and reasoning text remains opaque, grapheme-safe, and immediately completes when a turn ends.
* fix(android): preserve inverted timeline selection
React Native's prebuilt Android library does not consume source patches under node_modules. Register the compiled scroll manager before the core package so inverted child-reveal calculations leave focus and text selection in place while normal and explicit scrolling remain unchanged.
