//! Detection framework.
//!
//! CONTRACT for every module `detect/<name>.rs`:
//!
//! ```ignore
//! pub fn detect() -> crate::detect::Rows { ... }
//! ```
//!
//! * Return one `Row` per output line. Most modules return exactly one.
//! * Return an empty `Vec` when the info is unavailable — the line is skipped
//!   entirely (e.g. `battery` on a desktop, `swap` with no swap configured).
//! * `Row::val(v)` uses the default label supplied by `main`. `Row::keyed(k, v)`
//!   overrides the label (used when a module emits several distinct rows).
//! * Never panic and never block: read `/proc` and `/sys` on Linux, or go
//!   through `crate::sys` (sysctl/libSystem) on macOS; fall back to
//!   `crate::util::cmd(...)` only where no file/sysctl source exists.
//! * OS-specific modules provide one `detect()` per `target_os`; pure parsing
//!   helpers stay unconditional so tests cover them everywhere.
