feat(06-05): guidance/confirm/trip-end card builders + the token-only shell.css guidance block (GREEN)

- buildGuidanceCard: GUIDE register, verbatim headline, live telemetry row (MIN / {km} KM / ETA), 4px progressbar with full aria value set + instant inline width, no-reroute state line only when degrading, ONE btn-secondary END TRIP
- buildConfirmCard: GUIDE // CONFIRM + exact en/ms privacy copy, btn-primary YES ABANDON + btn-secondary CONTINUE, guide-confirm bottom-register hook — the ONE primary CTA in guidance chrome
- buildTripEndCard: GUIDE // END, exact deletion copy, no actions
- shell.css guidance block: banner chassis + 1px separator, CSS-only strip compaction under [data-guidance], list panel + row states + lamp, progress bar — token vars only, zero motion/depth/radius/hex (theme audit clean)
