    Add OSC 4 palette query, DECRQSS cursor style, and getpalette API

    OSC 4 query: when pY is '?', respond with rgb:RR/GG/BB at 8-bit
    precision matching internal storage.

    DECRQSS SP q: report current DECSCUSR cursor style (blinking/steady block/underline).

    getpalette: new ciolib API (uint8_t r/g/b) backed by bitmap_con,
    wired through all bitmap backends. Returns 8-bit values directly
    from the palette array.

    Also refactored OSC 4 set path: strncmp == 0 positive check instead
    of inverted break, cleaner if/else if/else structure for '?'/rgb/bad.

    Add movetext_clear() to fix status bar smear during scroll (ticket 228)

    New ciolib API: movetext_clear() moves text and atomically fills the non-overlapping source area with a caller-provided vmem_cell. Handles
    the general case of up to two clear rectangles (horizontal + vertical
    strips) for diagonal moves.

    In the bitmap fast-scroll path, the exposed pixel rows are cleared
    under screenlock so the display thread never sees stale data from the
    circular buffer wrap.

    cterm_scrollup() and scrolldown() now use movetext_clear() instead of
    separate movetext() + cterm_clrblk() calls.

    Also removes memset_u32() which used a slow memcpy-per-element loop.

    Add scaled graphics APC blits

    Add a ciolib blit operation that supports clipped integer scaling and
    x/y mirroring while leaving setpixels() as a strict compatibility
    wrapper.

    Use the new path for DrawPPM, DrawJXL, and P;Paste so graphics APC
    draws can clip off-screen destinations. Add FX/FY and ZX/ZY APC
    arguments, allow signed DX/DY destinations, document the revision bump,
    and mention the change in CHANGES.
