//! ix background daemon — ixd.
//!
//! Thin wrapper around [`ix::daemon::run_many`]. The full guarded daemon logic
//! (`LLMOSafe` `ResourceGuard`, entropy monitoring, Unix-domain socket,
//! file watching, beacon arbitration) lives in the library.
//!
//! ## Multi-root support (v0.8+)
//!
//! Pass multiple paths to watch several projects in one daemon process:
//!
//! ```text
//! ixd /home/user/project-a /home/user/project-b
//! ```
//!
//! Each root runs on its own thread with independent index, watcher, beacon,
//! and Unix domain socket. Signal handling and resource monitoring are shared.
//!
//! Safety guarantees (v0.1.2+):
//! - `SIGTERM`/`SIGINT` → clean shutdown (beacon removed, watcher joined, no zombies)
//! - `Builder::new` returns `Result` — no panics on unwritable `.ix` dir
//! - RSS ceiling in builder (512MB) — OOM protection
//! - TOCTOU guards in `process_file` — skips vanished/permission-denied files
