Release 0.4.0 - #21

Highlights

• Manage multiple local and SSH-backed Herdr servers from one bridge, with a per-browser active connection, isolated runtime state, persisted profiles, connection testing, automatic SSH supervision, and a connection manager UI.
• Push pane.agent_status_changed events per connection so agent working/idle/done transitions reach the browser immediately; hidden or unfocused pages refresh as soon as they become visible, focused, or back online.
• Refine dialogs and notifications; reload the page or PWA from the application menu.
• Fixes for Apple IME commits, Page Up/Page Down scrolling in fullscreen agents, and connection-scoped RPC isolation across server generations.

Verification

• bun run precommit (format, lint, typecheck, 558 tests) green
• All four platform packages built and inspected: archive checksums verify, VERSION reads herdr-gui 0.4.0 <platform>, executables are 755, --version prints herdr-gui 0.4.0
