Resolve browser compatibility and circular import issues

[lhapaipai]

Hi 👋

When consuming maplibre-geoman directly from sources (e.g. as a git submodule, without a prior build step), two runtime issues arise.

Changes

constants.ts — Guard process access in browser environments

process.env.VITE_GEOMAN_VERSION throws a ReferenceError in the browser since process is not defined outside of Node/Vite-shim contexts. The existing try/catch only handled the case where __GEOMAN_VERSION__ is undefined, not where process itself is absent.

// before
geomanVersion = (process.env.VITE_GEOMAN_VERSION as GeomanVersion) || null;

// after
geomanVersion = ((typeof process !== "undefined") && process.env.VITE_GEOMAN_VERSION as GeomanVersion) || null;

style.ts — Circular dependency caused by @/main.ts import

Importing FeatureShape, LayerStyle and SOURCES from @/main.ts (the package entry point) creates a circular module graph that causes an infinite loop at runtime. Each symbol is now imported directly from its source module.

// before
import { type FeatureShape, type LayerStyle, SOURCES } from '@/main.ts';

// after
import { type LayerStyle } from '@/types/map/layers.ts';
import { SOURCES } from '@/core/features/constants.ts';
import { type FeatureShape } from '@/types/features.ts';

Ok, thanks, it seems it required to check such imports across the project. IDE tries to auto-import everything from main.ts for some reason.
