Log Message:
syncdoom/syncduke: name the frame image-cache slot per-door

The SyncTERM APC cached-image Store used a shared "d.jxl"/"d.ppm" filename, so both doors reused the same client-side cache slot and it was opaque in SyncTERM's
on-disk cache. Name it per-door instead: syncduke_frame.jxl and syncdoom_frame.{ppm,jxl} -- self-descriptive and no longer colliding across doors. Still a single reused per-tier slot (re-Stored every frame), so no cache growth.

Log Message:
syncduke/syncdoom: sixel image centering + full-res sixel option

Two SyncTERM sixel improvements, tested live:

Centering (SyncDuke): the sixel image hugged the left edge on SyncTERM while SyncDOOM centered. Cause -- SyncTERM answers the graphics-canvas probe
(?2;1S) but not the cell-size probe (ESC[16t), so syncduke_term_cell_w()
stays 0 and termgfx_geom_center() can't turn the centered pixel offset into a text column, falling back to column 1. Give the centering the same 8x16 cell-size fallback the bottom-row reserve already uses (SyncDOOM always has), so the image centers; also drop the stale is-SyncTERM special case in the mouse-steer center (SyncTERM honors the sixel cursor like other terminals).

Full-res sixel (both doors): the default sixel encodes at half the display
size and lets SyncTERM nearest-neighbor-double it -- lean on the wire but
soft. Add a "sixel-full" tier that encodes 1:1 at the display size on
SyncTERM too (it was gated to non-SyncTERM), for a sharper image at ~4x the bytes. In SyncDOOM the JXL-start F4 cycle now offers both the half- and full-res sixel stops, so "sixel-full" is actually reachable.
