Symbol reference — JS bindings ↔ geos_c

GENERATED by scripts/gen-symbol-reference.ts (bun run docs:reference) from src/symbols.ts — do not edit by hand; the freshness test fails on drift. Binding rules (D15/F6/F10): const char* ARGS → cstring; GEOS-owned string returns → ptr + CString view + GEOSFree_r (a cstring return leaks); char returns mask & 0xff; INT returns (orientPolygons, minimumClearance, grid fractions, strtree nearest) are NOT masked; failed ptr returns are JS null, never 0.
