P11.3: glossier candy gem & selection feel (sx / iOS)

Browse Source 
Make the selection highlight read as glossy candy without new art and
without disturbing the idle-rest invariant. board_view's render_selection
layers a soft outward glow (two concentric stroked rings — the renderer has
no blur), a warm wash, a bright rim doubled by a thin inner highlight for a
glassy edge, and a wet sheen that rides the selected gem's live pose. Every
layer is a rect/overlay (issue 0002 forbids a draw-time gem-texture tint).

The gloss is selection-only: render_selection runs solely when a cell is
selected, so the resting board (no selection) is byte-identical to before
and the t==0 idle pose stays exactly the static sprite (locked by
tests/gem_pose). The selection-pop motion still comes from gem_anim; no
board / score / move state changes and input stays gated by BoardAnim.active.

Updated goldens/p6_select.png; README documents the P11.3 selection gloss
and its reproduce commands (reusing the P6.3 M3TE_SELECT + M3TE_ANIM_TIME
hooks).

The combo emphasis is purely visual and self-pruning: it never gates input
(`BoardAnim.active` owns gating) and never touches board / score / move state.
### Glossier gem & selection feel (P11.3)
The selection highlight (`board_view.sx` `render_selection`) is a candy-glossier
overlay: two concentric stroked rings fake a soft outward glow, a warm wash tints
the cell, a bright rim is doubled by a thin inner highlight for a glassy edge, and
a wet sheen rides the selected gem's live pose. The engine can't tint a texture at
draw time (issue 0002), so every layer is a rect/overlay — never a gem-texture
tint. The selection-pop motion still comes from `gem_anim`, so the **t==0 idle
pose is byte-identical to the static sprite** (locked by `tests/gem_pose.sx`); the
gloss is selection-only, so the resting board (no selection) is unchanged.
Capture it with the same P6.3 hooks — no new env var:
```bash
# Glossy candy selection on cell (3,3), pinned mid-pop: goldens/p6_select.png
env SIMCTL_CHILD_M3TE_ANIM_TIME=0.17 SIMCTL_CHILD_M3TE_SELECT=27 \
xcrun simctl launch booted co.swipelab.m3te
# Same selection at exact rest (no pop) — isolates the overlay:
env SIMCTL_CHILD_M3TE_ANIM_TIME=0 SIMCTL_CHILD_M3TE_SELECT=27 \
xcrun simctl launch booted co.swipelab.m3te
```
The selection gloss is purely visual: it never gates input (`BoardAnim.active`
owns gating) and never touches board / score / move state.
