feat: implement RFC-20 Phase 1 variable CRUD operations
Add a complete variable system for json-cas that provides mutable named
bindings to immutable CAS nodes.
Features:
- ULID-based variable identifiers (26-char Crockford Base32)
- Hierarchical scope validation (must end with /)
- Schema validation on update (prevents type mismatches)
- SQLite persistence (~/.uncaged/json-cas/variables.db)
- CLI commands: var create, get, update, delete
Implementation:
- Core types in variable.ts (Variable, VariableId)
- VariableStore class with SQLite backend
- Custom error types (VariableNotFoundError, SchemaMismatchError, etc.)
- Comprehensive unit tests (16 tests)
- CLI integration tests (12 tests)
- All outputs use JSON format
Test coverage:
- Variable creation with scope validation
- CRUD operations (create, read, update, delete)
- Schema consistency enforcement
- Error handling for all edge cases
- Full lifecycle integration tests
All tests pass (158 total), build clean, lint clean.
Fixes #21
