Remove constellation artwork, keep line traces only

Browse source 
Drops the 12 zodiac PNGs, their loader/similarity-transform renderer and
the art anchors in constellations.js; build_constellations.py no longer
emits art data. Constellation mode now shows just the Stellarium traces,
labels and stars.

| Realistic sky (stars) | `<canvas>`; real-time alt-az projection of `starcatalog.js` (8,404 Yale BSC stars, V ≤ 6.5) for the configured lat/long (default Toledo-PR). Static layer pre-rendered offscreen with triple-buffer + 1.4 s crossfade between reprojections (every 30 s; 4 s during timelapse/camera rotation); bright stars twinkle per frame. Debug: `window.__skyTimeOffset` (ms) fast-forwards the sky |
| Milky Way | Per-pixel sampling of `milkyway.jpg` (Gaia photo, full res): `buildMwGrid` caches viewport unit vectors + extinction/glare, `renderMilkyWay` applies only the sidereal rotation (camera azimuth folded into the equatorial→galactic matrix) and stylized "development" (deep blacks, saturation, cool shadows). Decoded texture stays resident (~75 MB) |
| Moon & planets | Astronomy Engine topocentric ephemerides: Moon with real phase texture + bright-limb angle, 7 planets with magnitude-scaled dots (labels only in constellation mode) |
| Zodiac constellations | Stellarium Modern lines + anchored PNG art (similarity transform, no shear); toggled via `/tmp` file or `C` key |
