/**
 * pi-mind postinstall / host-project wiring logic.
 *
 * Extracted from bin/init.js so the postinstall script stays a thin
 * wrapper while the actual file/symlink logic is unit-testable. The
 * postinstall wrapper handles:
 *   1. process.exit(0) on PI_MIND_SKIP_INIT=1
 *   2. host-root detection (INIT_CWD + pnpm-aware walk)
 *   3. printing the "ready" banner
 *
 * Everything in this file is pure: takes explicit paths, returns a
 * structured result, no process.env reads, no side effects beyond
 * filesystem mutations. Testable in tmp dirs.
