Turn status: moon-phase spinner for Waiting for response

The active-turn spinner next to "Waiting for response…" now cycles
the moon phases 🌑🌒🌓🌔🌕🌖🌗🌘 — the official kimi-cli's lunation
animation (rich's `moon` spinner) — matching the welcome-screen moon
logo. New glyphs::moon_spinner_frames() with the same legacy-ConHost
ASCII fallback as every other spinner set; emoji frames are 2 columns
and the status row already measures the rendered frame, so layout
adapts. The ambient "Starting session…" row and other spinners stay
braille.

Verified: kigi-tui lib 6621 + pager-render 963 tests green; real-binary
PTY e2e waiting_for_model_label_shows_before_first_token passes with
the new spinner rendering in a live vt.
