Erik 991fb9a222 tools(probe): add StarsProbe to dump every SkyObject's geometry + UVs
Sibling of WeatherEnumerator/PesChainAudit. Walks every DayGroup in the
Dereth Region (0x13000000), prints each SkyObject (Properties bits,
TexVelocity, BeginTime/EndTime, gfx/pes ids), then dumps the underlying
GfxObj's vertices, UV ranges, and surfaces. The crucial diagnostic is
the per-GfxObj "UV range outside [0,1]" flag.

Built for Bug B (sky-investigation-handoff §"Bug B"): stars rendering as
a square in one corner of the sky. Smoking gun on first run: GfxObj
0x010015EF (OI-1 in every DayGroup, TexVelocity = 0) has UVs in
[0.398, 4.602] — meaning the texture tiles ~4× across each face, but
SkyRenderer's "CLAMP_TO_EDGE unless TexVelocity != 0" heuristic forces
clamp on it, so the whole inner dome samples edge texels except the
tiny region where UVs happen to fall in [0,1]. That tiny region is the
"square in one corner" the user observed.
