Fix __publicField error with esnext esbuild target

Browse Source 
maplibre-gl v5 bundles reference __publicField and other esbuild
class-field helpers without defining them — a known upstream bug
(maplibre-gl-js issue #6680). Setting esbuildOptions.target and
build.target to 'esnext' tells esbuild to emit native class fields
instead of helper-based transforms, eliminating the missing symbol.

Remove all previous workaround attempts (define rewrite, globalThis
polyfill in index.html).
