Unified facade crate for the published RustUse set facades.

rustuse gives one dependency surface across the repository-level RustUse facade crates that are already live on crates.io. It keeps direct child-crate reexports for the child-rich sets and adds facade-only grouped modules for every published set facade.

• set-level facade modules for all published repository-level use-* crates
• child-rich set surfaces from use-chemistry, use-constants, use-math, use-net, use-pattern, use-rust, and use-web

The crate re-exports published crates at the top level and also groups them by set so consumers can choose the style they prefer. Geometry is available both as its own set module and through the existing rustuse::math::geometry compatibility path.

[dependencies]
rustuse = "0"

Disable default features if you only want one set:

[dependencies]
rustuse = { version = "0", default-features = false, features = ["constants"] }

Or enable one of the facade-only set modules directly:

[dependencies]
rustuse = { version = "0", default-features = false, features = ["time", "wave"] }

# fn main() {

use rustuse::use_isotope::isotope_by_symbol;
use rustuse::use_combinatorics::factorial;

use rustuse::use_match::{MatchSpan, slice_match};

• rustuse::chemistry, rustuse::constants, rustuse::math, rustuse::net, rustuse::pattern, rustuse::rust, and rustuse::web keep the richer grouped access for the published child crates that rustuse already re-exports directly.
• rustuse::math::geometry remains available as a compatibility alias for use-geometry.

The published rustuse 0.1.3 release covers the earlier chemistry, constants, math, net, pattern, rust, web, and initial set-facade surface. The current main branch expands the default full feature to the full set of repository-level RustUse facade crates that are already published on crates.io.

The child-rich sets continue to use local path dependencies for the focused crates that rustuse re-exports directly. The facade-only set modules use crates.io version pins so the published integration surface can coexist cleanly with local sibling workspaces that reuse crate names in different domains.
