Backend reset() method

Category: reset · Baseline: core

Tests whether the terminal backend provides a programmatic reset method that returns the terminal to a clean initial state. This is specific to the Termless testing framework — it verifies that the backend can be reset between test cases.

How this is testedautomated
Write text, call backend reset() method, verify cursor returned to (0,0). Specific to the Termless testing framework.

The same probe runs against headless backends (via Termless) and real terminal apps (via a daemon launched in each terminal). This lets us distinguish parser correctness from rendering correctness.
