UX polish batch 2 (plan workstreams D/E5/E6): - D: a mouse/keyboard game library page over pf-client-core::library (the GTK ui_library.rs counterpart): responsive 2-6 column poster grid (2:3 portraits, store badge, monogram placeholder while art streams in), loading / error+retry / empty / grid states, tap-to-play via a normal spawn carrying --launch id. Poster bytes land in a disk cache (%LOCALAPPDATA%\punktfunk\art-cache) so the Image widget loads file:/// URIs (reactor has no from-bytes source) and revisits render instantly. Reached from a paired host's "Browse library..." menu item behind the new "Show game library (experimental)" Settings toggle (the shared library_enabled field, Apple/GTK parity). A Shared::library_gen generation guard keeps a superseded fetch from publishing (speed-test pattern). - E5: the session window opens at the shell's own top-left (--window-pos, new SessionOpts::window_pos) instead of centered on the primary display - streams land on the monitor the shell is on, and the hide/restore handoff reads as one window changing content. Fullscreen follows that display. - E6: the Help shortcuts add Alt+Enter and the controller escape chord (LB+RB+Start+Back, hold to disconnect). Also: rustfmt normalization of the merged probe helper.
