funman300 763fdb486f fix(input): hit-test deck at correct position; accept waste click too ...

pile_positions[KlondikePile::Stock] stores the waste column position
(col_x(1)).  card_plugin renders the face-down deck one column to the
left (col_x(0) = Tableau1 x) via `base.x -= tableau_col_step`.

handle_stock_click and handle_touch_stock_tap were using pile_positions
[Stock] directly, so the click hotspot was on the waste card (right
column) instead of the deck (left column).  Result: clicking the
visible face-down deck did nothing, while clicking the waste pile
triggered draw.

Fix: compute deck_pos = Vec2::new(tableau1.x, waste_pos.y) and hit-test
both the deck column AND the waste slot.  Accepting waste clicks matches
standard Klondike UX where either card acts as the draw trigger.

Touch tap handler receives the same fix.

Also rebuild canvas_bg.wasm with the corrected engine source and
-O2 optimisation (replacing the previous -Oz that caused grey screen).
