Status messages now use a sequence counter so rapid actions don't
cause premature clearing. Detail pane shows scroll position and
supports pgup/pgdown/g/G. Capture drawer border includes inline
label. Cards view groups by intent (pinned/grab/read/fill) with
gutter labels matching the stream view's date grouping pattern.
Detail pane now pipes entity body through charmbracelet/glamour for
styled markdown output — headers, bold, code blocks, lists. Uses
hardcoded dark style to avoid terminal query freeze in alt screen.
Header now renders stream/cards as tabs with keybindings inline —
active tab highlighted, inactive shows the key to switch. Footer
shows a capture tab affordance when in list state. Redundant mode
and capture hints removed from the context hint bar.
Content area now enforces full height so the context help bar stays
pinned to the terminal bottom. Hint keys rendered with bold highlight
color for scannability. Status messages (created, deleted, etc.)
auto-clear after 2 seconds, reverting to the entity count.
