- Installer: one `cargo install maestro` instead of two; ExecStart becomes
`~/.cargo/bin/maestro daemon`; user unit renamed `maestrod.service` →
`maestro.service`; configure step is `maestro daemon configure`.
- E2E harness: both `Daemon` and `Registry` subprocess wrappers shell out to
the unified `maestro` binary with the appropriate subcommand.
- State dir: `~/.local/state/maestrod` → `~/.local/state/maestro`.
- Docs: CLAUDE.md repo layout, design spec repo layout + "Daemon (`maestro daemon`)"
heading, INSTALL.md (full rewrite of CLI references + new thin-builds section).
