Why

A blinking cursor rendered steady, so a video of an idle prompt looked frozen rather than live.

What

--cursor-blink (off by default): follows the config's cursor.blink mode (program/never/always) and cursor.blink_interval_ms like a felis window, with the phase taken from the output timeline (timeline::Blink) and restarted at each recorded cursor_state frame. The same recording blinks on the same frames every time.
Off by default so idle stretches stay identical and the GIF sink can merge them.
Golden test a_blinking_cursor_is_hidden_in_its_off_half (frames 10 visible, 20 hidden); unit tests for the phase and the 50 ms floor.
Design, README and backlog updated.

Verification

fmt, clippy, tests green locally. pi review (luna): PASS, no findings.

A recording of a blinking cursor rendered steady, so a video of an idle
prompt looked frozen rather than live. --cursor-blink follows the
config's cursor.blink mode and interval like a felis window, but takes
the phase from the output timeline and restarts it at each recorded
cursor_state frame, so the same recording always blinks on the same
frames. Blinking stays opt-in: a steady cursor keeps idle stretches
identical, which is what lets the GIF sink merge them.
