cvx-core — Core types, traits, configuration, and error handling for ChronosVector.

This crate defines the foundational abstractions used across all other CVX crates. It has no dependencies on other workspace crates — all other crates depend on it.

Modules

• [types] — Core data types: [TemporalPoint], [DeltaEntry], [EntityTimeline], [ChangePoint], [ScoredResult]
• [traits] — Trait definitions: [DistanceMetric], [VectorSpace], [StorageBackend], [IndexBackend], [AnalyticsBackend]
• [config] — Configuration: [CvxConfig] (deserializable from TOML)
• [error] — Error types: [CvxError], [CvxResult]

Design Principles

• Domain-agnostic: CVX knows about temporal vector trajectories, not about finance, NLP, or medicine. Domain-specific concepts are compositions of these primitives.
• Typed errors: Every subsystem has its own error type that converts into [CvxError].
• Serializable: All core types implement serde::Serialize + serde::Deserialize.
