/**
 * THE CORE PUBLIC API — the only module the shell (app/, components/) may
 * import. Everything exported here is browser-safe: pure logic + types,
 * no node builtins, no fs, no network.
 *
 * Server-side surfaces (chat streaming, store reads) live behind
 * src/server's barrel instead — the import law (eslint.config.mjs):
 *
 *   components/**  →  "@/src/core"        (this barrel, ONLY)
 *   app/**         →  "@/src/core" + "@/src/server"
 *
 * Server-only core modules (core/graph.ts emission/derivation,
 * core/graph-context.ts) are pure but need storage ports passed in by a
 * server caller, so they are deliberately NOT re-exported here — the
 * server imports them directly. The storage PORT TYPES are types-only and
 * browser-safe, hence re-exported.
