feat(config): add Zod schema validation and JSON Schema generation

- Add Zod schema for oh-my-opencode.json configuration validation
- Generate JSON Schema at build time for IDE autocompletion
- Add safeParse validation with error reporting on config load
- Export OhMyOpenCodeConfigSchema for programmatic usage
- Add build:schema script and ./schema.json export
- Update README with $schema usage documentation
