…escing

Four small daemon/dialog correctness fixes.

`dialog::box_rect` (#9)
- Clamp dialog height to the area below the status bar so a very
  small terminal does not paint past the bottom edge (which would
  scroll the host terminal and destroy the operator's pane content)
  and does not overlap row 0 (the brand pill / tab strip). Trade-off
  is that the dialog renders unusable when the terminal is
  pathologically small, but the host terminal stays in a recoverable
  state regardless.
- `render_bottom_hint`: tighten the bail to `total > term_cols` so
  an exact-fit hint renders instead of being dropped at `==`. Use
  saturating subtraction for the start_col centring math.

`Multiplexer::spawn_session` (#34, cap side)
- Cap tabs at `MAX_TABS=32` and sessions at `MAX_SESSIONS=64`. A
  runaway client (or an operator mis-click loop) cannot allocate
  unbounded PTYs — each session retains scrollback, a master+slave
  PTY pair, and a child process, so unbounded growth is a real OOM
  risk. The CLI surface returns an `anyhow::bail!` which
  `dispatch_spawn_intent` already clog's.

`SessionEvent::Output` (#36)
- Move `drain_mode_transitions` inside the `is_focused` gate. The
  previous code drained and discarded the bytes on every backgrounded
  pane — wasted work, plus a future change that reads
  `bracketed_paste_active` after drain on an unfocused pane would
  silently see the wrong state. Also restructured to collect the
  to-emit bytes into a local Vec so the `&mut Session` borrow ends
  before `mux.send_output` (which needs `&self`).

Render ticker (#37)
- Drop the `mux.dialog.is_none()` gate from the render ticker
  condition. `compose_frame` already includes the dialog overlay
  when one is open, so the open-dialog path now composes at the
  normal ~30 fps instead of accumulating `dirty` until dismiss —
  without this the dismiss frame was a sudden jump of N frames'
  worth of accumulated PTY output that the operator had no way to
  see coming.
