gramps b93744ec7f feat(65): the replay ring — encoded fragments in RAM, capped by bytes ...

Slice 1 of TASK 65, pure memory, no encoder change yet.

A 1080p BGRA frame is 8.3 MB, so fifteen seconds of raw composite is ~7.4 GB — the 15 MB figure in the
spec is the *compressed* stream. So the ring holds fragmented-MP4 bytes that ffmpeg will write to a
pipe, and a save is init-segment + surviving fragments in order.

Two rules the tests pin: the cap is by **bytes** (bitrate moves; seconds do not), and the newest
fragments always win, because a clip that ends at the keypress is the entire point. The init segment does
not rotate and cannot be reused across encoder starts, so `Clear` drops it too — an MP4 without its moov
is noise.

Next slice: ffmpeg writes the buffer output to stdout while `-stats` stays on stderr, and the pump feeds
this ring. Not done here on purpose — an encoder change is the riskiest edit in the app and deserves its
own commit and test.
