BREAKING: environment bindings are validated once at construction. Bindings is an opaque validated collection built by bindings or prefixedBindings; envSource and readEnvSource take Bindings and are total; environmentSource and readEnvironmentSource provide the conventional "environment" label; bindingsList inspects a validated collection.
Add renderEnvErrorText and renderEnvErrorsText for stable, operator-readable, value-free binding diagnostics.
Add mergeBindings: combine validated Bindings collections with re-validation of cross-collection conflicts, enabling derived and hand-written bindings to compose.

Initial experimental release.
Add explicit environment bindings, injected snapshots, and trusted Kubernetes object annotations.
