Three-crate workspace per SPECS.md. varde-proto defines the full JSON
Lines protocol (requests, envelopes, structured errors, events) with
string-typed hashes so the crate carries no iroh dependency. The daemon
binds its unix socket, loads config with flags > env > file > defaults
precedence, and answers status/list; everything else returns a
structured "unimplemented" error. varde-ctl maps subcommands 1:1 onto
requests and round-trips status against a real daemon in the tests.
Dependencies: serde/serde_json (wire format), tokio (async runtime and
unix sockets), tracing/tracing-subscriber (structured logging), toml
(config file), anyhow (binary-edge errors), thiserror (reserved for
library errors), clap (ctl flag parsing, per spec), tempfile (dev-only,
ephemeral test dirs).
