v0.4.3

Added

• Per-workspace app rules: an optional workspace matcher (by index or name) scopes an app rule's class and click-action overrides to a single workspace.
• Proportional button sizing: proportional_button_width sizes each button to its window's on-screen width in the niri layout, with proportional_icon_size to scale icons along with it.
• toggle-title click action to show or hide an individual button's title.
• toggle_title_rules to automatically collapse titles for windows matching app/title patterns.

Fixed

• Audio indicator now stays on the window playing audio instead of following focus.
• Audio indicator now appears for X11 apps and native PipeWire clients.
• Audio indicator no longer shows on every window of the same app.
• Floating window buttons no longer jump to follow focus.
