Extends the automation-selection keyboard hook with Cmd/Ctrl+C (copy the active range) and Cmd/Ctrl+V (paste onto the selected clip's lane, at the selection's start or the playhead, chaining the selection to the pasted span so a second paste lands right after the first). Paste falls through untouched when no target lane resolves, so clip-level paste keeps working. Also fixes a latent test-isolation bug: setup() never unmounted the previous test's Host, so document keydown listeners leaked across tests and could consume later events before the current test's own listener ran.
