/**
 * `@czap/command/host` — Node host execution for the command registry. The
 * canonical home for spawn, the vitest runner, the ffmpeg render backend, the
 * idempotency cache, manifest-path resolution, and the shared
 * `createNodeCommandContext()` factory. The CLI and MCP adapters both build
 * their injected I/O from here; neither hoards host infra, and the MCP server
 * never imports the CLI.
 *
 * Importing this pulls Node-coupled code (child_process, fs, ffmpeg). The pure
 * `@czap/command` main entry (registry, descriptors, handlers, types) does NOT
 * import this — keep that boundary intact.
