    Log Message:
    syncdoom: skip redundant per-cell SGR in the text/block renderer

    The text tier emitted a full color escape for every cell. Track the last foreground/background actually sent and emit only the component(s) that
    changed -- a flat run now emits just the glyph -- cutting output bytes
    sharply over a BBS link with identical on-screen results. The cache is
    reset at each \033[0m (row end) and at frame start, where the terminal is
    back to its default colors. Also drops the now-unused buffer_append_format.
