Audit Finding (Architecture, Low)

Location: crates/agnix-wasm/Cargo.toml:19

agnix-wasm declares agnix-core with default-features = false, which looks like no_std support. But agnix-core still requires std. This creates confusion.

Fix: Document in agnix-core's Cargo.toml and README that the filesystem feature only controls file I/O dependencies (rayon, ignore, dirs), not std compatibility.
