calic ddafcd6486 feat(bake-sprite): --pixels-per-meter <N> embeds atlas_meta in sprites.uv.json ...

Sprite-mode bake gains an additive --pixels-per-meter flag. When set,
the value is written into sprites.uv.json under atlas_meta.
pixels_per_meter. Consumers (lib-core.render path-1 via per-entity
sprite_scale) divide their project canonical px/m by this number to
auto-scale the rendered quad — atlas-native resolution no longer needs
to match the project tile-scale.

Unset (legacy bakes): atlas_meta omitted, byte-equal to v0.3.0 output.

Tests: 53/53 pass; existing buildUvJson test continues to assert the
unset-default shape.
