v0.2.1

Fast scrollback currently rebuilds every visible terminal cell for each wheel event, which can stall the UI; multiline paste is silently rejected when the remote application has not enabled bracketed paste. Session tabs also lack a close control.

This release batches terminal frame refreshes, adds a draggable history scrollbar and a close control to each session tab, and supports multiline paste with normal terminal line endings. Exited sessions close immediately; closing running or connecting sessions through the tab, Ctrl+W, or the Session menu requires confirmation. Ctrl+Q also confirms before disconnecting live sessions, with Cancel focused by default.

The package and lockfile are bumped to 0.2.1, and the changelog and installation instructions are updated. The existing changelog test now checks its original 0.2.0 entry so newer releases can be added.
