[v1] Create public library API for codec, signing, verification, and RPC parsing #58
Description
Problem
The v1 release needs this work to make the toolkit claim defensible.
Scope
- Create the stable public Zig library surface for v1.
- Export only toolkit APIs needed for serialize, signing-hash, verify, and selected RPC parsing.
Files
- src/modules.zig
- src/
- build.zig
Gates
- Gate A
Acceptance Criteria
- Stable exported functions exist for serialize, signing hash, verify, and selected RPC parsing.
- Examples compile against the public API.
- Internal-only modules are not exposed accidentally.
