Greentic deployment object-model schemas.

See plans/next-gen-deployment.md §5 for the design rationale. This crate is the single owner of the Environment, Revision, TrafficSplit, BundleDeployment, Credentials, PackConfig, and RuntimeConfig types. Other crates depend on it; nothing in this crate depends on operational or runtime code.

greentic-deploy-spec

Schema crate for Greentic's deployment object model. Defines:

• Environment (§5.1) + EnvironmentHostConfig + EnvPackBinding + CapabilitySlot + PackDescriptor
• EnvironmentRuntime (§5.1a)
• Revision (§5.2) + RevisionLifecycle + transition predicate
• TrafficSplit (§5.3) + basis-points validator
• BundleDeployment (§5.4) + revenue-share validator
• Credentials (§5.5)
• PackConfig (§5.6) — non_secret + secret_refs + runtime_refs
• RuntimeConfig (§5.7) + RevisionRuntimeBlock

This crate is the single owner of these schemas. Other crates depend on it; nothing in this crate depends on operational/runtime code. JSON-schema generation is gated behind the schemars feature and a thin gen-schemas binary.
