tc-value

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.

Current status

• Canonical Value enum implemented with variants:
  • None
  • Bool
  • Number
  • String
  • Link
  • Map
  • Tuple
• destream/JSON round-trip support for all variants.
• Bool-as-number semantics: JSON booleans decode as Value::Number(Number::Bool(...)).
• Unit tests for literal and nested map/tuple round-trips.

Encoding notes

• None, Bool, Number, and String encode as plain JSON literals.
• Map encodes as a plain JSON object of nested Values.
• Tuple encodes as a plain JSON array of nested Values.
• Link encodes as a single-entry map keyed by the link path (v1-compatible form).

Typed value envelopes (/state/scalar/value/...) remain accepted where required for compatibility, but canonical emission prefers the plain JSON forms above.
