refactor: replace exportName with name throughout codebase

- Update TpmjsToolDefinitionSchema to only use 'name' field
- Add 'sandbox' as valid category for sprites tools
- Update all package.json files to use 'name' instead of 'exportName'
- Update documentation and source files accordingly
- Add 11 new sprites tools for sandbox/code-execution
