Three TUI-polish items. - OUTPUT free-scroll: PgUp/PgDn (and ^u/^d half-page) scroll the transcript back through history; esc snaps to tail-follow. outputScroll is clamped against outputViewport(), which mirrors View/renderMain geometry, so the edges land exactly (no dead presses unwinding an overshoot). routerRows split into buildTranscriptRows (full render) + windowing so the handler measures the same content. Tests cover the clamp + the fits-in-panel no-op. - Help overlay: `?` (or the "help" palette command) opens a keybinding cheat-sheet grouped by context (session / overlays / approval band) — the non-palette keys especially. Any key dismisses it. - Event-inspector filter: `/` filters the event list by a case-insensitive substring of type/detail (currentEvents applies it); `c` clears, esc stops editing then closes. Fresh per open. EVENTS side panel stays unfiltered. go build / vet / test green; rendered help + filtered inspector via cmd/preview (help, events-filter kinds).
