Both desktop-app's app.rs and the new Android transcript client (RUST.md's I5) need the same page-fold and live-stream resume-cursor logic; per CODE_RULES's "write the logic once" it now lives in client-core alongside fold_event/group_tool_runs instead of being duplicated. desktop-app calls the shared functions; its own copies and their tests moved with them. Also fixes a clippy::collapsible_if in config.rs's percent_decode, found while re-running clippy after this change (let-chains are stable now). Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
