Core value representations shared across TinyChain crates. This crate will house
the canonical Value enum (numbers, strings, tuples, etc.) used by the IR,
state subsystem, and adapters.
- Stub
Valueenum with initial variants (e.g.,Number). - Implement numeric support using
number-general. - Add serde/destream implementations so
Valuecan flow across adapters. - Wire unit tests and cross-crate integration tests once the initial API stabilizes.
