Each hex now gets a meta/<q>_<r>.json with stable ID, pixel center
coordinates, pixel bounds, labels, notes, and classification status.
The pixelCenter acts as a scale-independent anchor: when switching from
10 Meilen/Hex to 5 Meilen/Hex, pixelToAxial(meta.pixelCenter, newSize)
maps coarse hexes to fine hexes without re-running classification.
Adds:
- pipeline/build-hexmeta.ts: creates/updates metadata + exports
data/hexmeta-<map-id>.jsonl (committed, survives git clones)
- pipeline/auto-classify-ocean.ts: pixel-based ocean auto-detection
- pipeline/create-map.ts: one-off DB map entry creation
- extract-submaps.ts: writes meta/<q>_<r>.json during extraction
- data/hexmeta-1.jsonl: 8844 hex metadata entries for Aventurien map 1

Adds a 3-phase pipeline to populate a HexMap from a source image using
Claude's vision capabilities instead of naive pixel-color matching:
Phase 1 (extract-submaps): crops annotated submap PNGs per hex,
including center + 6 neighbours with SVG overlay.
Phase 2: Claude classifies submaps in a Code session, writing
classifications.json — resumable across sessions.
Phase 3 (import-from-json): reads classifications.json into the DB.
Also adds assemble-map.ts to reconstruct a full image from a Leaflet
tile pyramid (used to recover the Aventurien source map from kiepenkerl).
Adds CLAUDE.md documenting the approach, scale constants
(PIXELS_PER_MEILE=8, hexSize=40 = 10 Meilen/Hex), and the
Nord/Mitte/Süd region split for the Aventurien map.
