/**
 * @claude-flow/cli postinstall — agentdb compatibility patches.
 *
 * Two patches applied to the user's installed agentdb tree:
 *
 * 1. Sibling directory copy (#1721 fix): agentic-flow's runtime patch
 *    expects agentdb's controllers + utils + core + services + types
 *    at `dist/<name>/` (legacy v1.x layout). agentdb v3 ships at
 *    `dist/src/<name>/`. Copy each `dist/src/<name>/` subdir to
 *    `dist/<name>/` so the legacy import paths resolve. Skip dirs that
 *    already exist so this is idempotent.
 *
 * 2. Exports-field augmentation (ADR-095 G7): six controller files
 *    exist in agentdb's dist but are not declared in its package.json
 *    `exports` field — `AttestationLog`, `MutationGuard`,
 *    `GuardedVectorBackend`, `GNNService`, `RVFOptimizer`,
 *    `GraphAdapter`. Without these declared, Node's strict exports
 *    enforcement blocks subpath imports even when the file is on disk.
 *    We add the missing entries (only if the file actually exists)
 *    so consumers can reach them via `agentdb/controllers/...`.
 *
 * Both patches are best-effort — failure to apply does not break
 * install (try/catch wraps each phase). Re-running is safe.

 * agentdb (different versions) at different levels. Only patching the
 * resolved one leaves consumer code that imports through a different
 * resolution path with stale exports.
 *
 * Strategy: walk up from the postinstall script's directory, collect any
 * `node_modules/agentdb` we find along the way + the .pnpm cached copies
 * directly under the same node_modules/.pnpm/ root.
