Two visible regressions in the in-game map's fog overlay surfaced
on dev-deploy:
1. With three LOCAL planets close together, only the last planet
glyph stayed visible inside the bg holes — the other two were
obscured. The previous implementation stacked the fog rectangle
plus every bg circle onto a single `Graphics` via repeated
`g.rect(...).fill(...).circle(...).fill(...)...`. Pixi v8's
multi-shape Graphics is supported in theory, but in practice
only the last shape's fill seems to land, dropping the earlier
bg holes (and the planet glyphs on top look like they vanished
along with their hole). Splitting each op onto its own
`Graphics` inside a per-copy `Container` removes the ambiguity
— one shape, one fill, one render pass.
2. A planet near the right world edge produced a "sector" — the
bg circle painted into the area past the seam, but the
neighbouring tile's fog rectangle then overpainted that bleed,
leaving a quarter-circle hole. In torus mode each visibility
circle is now drawn at the nine wrapped positions
(`(dx, dy) ∈ {-1, 0, 1}²`); the wrapped copies in the
neighbour-tile-aligned positions keep the hole continuous
across the seam. No-wrap mode keeps a single emission per
circle, because wrapped circles would leak into the visible
world rectangle as unwanted holes.
The `fogPaintOps` helper now takes the wrap mode as a parameter;
`tests/fog-paint-ops.test.ts` covers the torus expansion
(nine-wrap product per circle, the seam-fix case at x = 950) and
re-asserts the no-wrap path.

Lifted the Phase 29 fog draw sequence out of `setVisibilityFog`
into a pure `fogPaintOps` helper that returns an ordered list of
fill operations (one fog rect, then one background-coloured
circle per visibility entry). The renderer now dispatches each op
straight onto a Pixi `Graphics`; the indirection lets the layered-
overpaint contract be tested without booting Pixi.
`tests/fog-paint-ops.test.ts` covers: empty input → no ops; single
circle → fog rect + bg circle in that order; multiple circles → N
bg circles after the fog rect; overlapping circles emitted
independently (the rendering order unions them); zero / negative
world dimensions → no ops.
