CLI vs compilerd params (split-brain backlog)

CLI vs compilerd params

Today: crates/vox-cli/src/cli_args.rs (clap) and crates/vox-cli/src/compilerd.rs (Deserialize bodies) mirror overlapping flags/options.

Target: one contract-backed shape (or a single Rust struct carrying both clap::Args + serde) so CLI argv and daemon JSON cannot drift.

Guardrails until merge: vox ci command-compliance keeps registry / reachability / MCP wiring aligned; changing either surface requires updating both files deliberately.
