    termgfx: refresh sixel palette-mode comments for the tri-state

    Comment-only cleanup following the SIXEL_PAL_NONE/FULL/USED tri-state
    that replaced the old 0/1 boolean:

    - termgfx_termio.c: the g_rgbx_pal scratch comment said emit_pal is
    "always 1"; present_rgbx() actually always passes SIXEL_PAL_USED
    (the used-colour subset), so say that instead.
    - sixel.h: sixel_encode()'s doc comment said "pass zero otherwise",
    predating the tri-state; reworded to name SIXEL_PAL_NONE.
    - termgfx_termio.c: the full-frame emit_pal assignment had two
    stacked, overlapping SyncTERM-rationale comment blocks (an older
    "persists sixel color registers" block immediately followed by a
    newer "FULL only on a real palette change" block covering the same
    ground). Merged into one concise block; no content lost.

    No code lines touched.
