slice 8A (controller half): bootstrap.json ingestion + pinned agent local-API client (v0.35.0)

internal/bootstrap: first-run bootstrap.json ingestion (decision (c)) — seed
controller.yaml + skip setup; idempotent + fail-safe. internal/agentapi:
minimal pinned local-API client (leaf-cert SHA-256 pin, fails closed). config
LocalAPIConfig; startup /storage connectivity probe.
