/**
 * ADF Compiler — renders modular .ai/*.adf source trees to flat vendor agent-config files.
 *
 * "Babel for agent configs" — ADF is the source of truth, vendor files are build artifacts.
 *
 * Architecture: pure core with no runtime dependencies (zero-dep package constraint).
 * - All I/O is injected (readFile), so the module is fully testable without touching disk.
 * - Output is deterministic: same inputs → byte-identical output.
 *
 * Zod validation lives at the CLI boundary (adf-compile.ts), not here.
