v0.2.1

Added

• Herdr now checks for updates at startup and periodically while it stays open, so long-running sessions can still discover new releases without a restart cycle.
• Added a lightweight bottom-right toast when an update has been downloaded and is ready, with a simple restart-to-use-it flow.

Changed

• Rendering is now driven more directly by app events instead of relying as much on polling, which makes the UI feel snappier and cuts unnecessary redraw work.

Fixed

• Restored smooth fast spinner animation for working agents.
• Closing a pane or workspace now reliably terminates the processes running inside that pane session instead of leaving shells or child processes behind.
• Fixed bracketed paste handling so incomplete paste sequences are preserved across read timeouts instead of being dropped or misread.
