Log Message:
syncduke: fix banner-draw stack over-read on wide terminals

syncduke_node_draw padded the text to `cols` (up to 128) with %-*.*s; on a
terminal wider than ~106 columns the formatted line plus escape bytes exceeded
the 128-byte stack buffer, so snprintf truncated but returned the full intended
length and syncduke_out_put then memcpy'd that many bytes -- reading past the
buffer and shipping stack garbage (and cutting the SGR reset, leaving the
terminal white-on-red). Switch to SyncDOOM's draw_page_overlay pattern: erase-
to-EOL (\x1b[K) fills the strip to the true terminal edge with a bounded byte
count, independent of `cols`. Fixes the over-read and the wide-terminal under-
fill in one change.
