scc-plugin-api 0.2.7

Stable SCC plugin contracts: manifest, permissions, operation declarations
Documentation

Stable SCC plugin contracts (spec sections 15-16, 21, 31).

Plugins depend on THIS crate only — never on scc-engine or scc-cli. Manifests are scc-plugin.toml; the process-plugin wire protocol is plain JSON over stdio using [PluginRequest]/[PluginResponse].
