This adds basic support for window functions. For now: * Only existing aggregate functions can be used as window functions. * Specialized window-specific functions (`rank`, `row_number`, etc.) are not yet supported. * Only the default frame definition is implemented: `RANGE BETWEEN UNBOUNDED PRECEDING AND CURRENT ROW EXCLUDE NO OTHERS`.

Testing Extensions
When adding tests for extensions, please follow these guidelines:
- Tests that verify the internal logic or behavior of a particular extension should go into
cli_tests/extensions.py. - Tests that verify how extensions interact with the database engine, such as virtual table handling, should be written
in TCL (see
vtab.testas an example).
To check which extensions are available in TCL, or to add a new one, refer to the tester.tcl file and look at the extension_map.
