rusty-capability-attr 0.1.3

Layer 2 (side-effect / capability safety) #[capability(...)] proc-macro attribute for Rust: declares and enforces a function's allocation/IO/raw-pointer scope at compile time, orthogonal to unsafe. Phase 1 (stable Rust, no rustc changes) of docs/aisecurity/capability-rfc-updated.md, scoped to userspace (git.git) needs — see this crate's own module docs for what was dropped from the RFC's embedded-oriented vocabulary and why.
