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.

// Package bootstrap implements first-run bootstrap.json ingestion (slice 8A, doc 03 §6,
|
||||
// config-contract decision (c)). The host agent's provisioning back-half writes a stable
|
||||
// bootstrap.json into a read-only config mount; on first run the controller seeds its own
|
||||
// controller.yaml from it and comes up CONFIGURED, skipping the setup wizard. The agent emits
|
||||
// the stable contract; the controller owns the translation — the two stay decoupled.
