rusty-capability-core 0.1.0

Internal-only capability vocabulary (AllocLevel/IoLevel/PtrLevel/CapabilitySet), body-usage inspector, and declared-vs-detected subset check shared by capability-attr and taint-generate. Published only so those crates resolve from crates.io — no public-API/semver guarantee; extracted from capability-attr's own private modules, which a proc-macro = true crate could never expose to begin with.
