feat: natural zoom bindings and improved tmux session reuse

[berrimi]

Enhancements: Smooth Zoom and Improved tmux session handling
This PR introduces two quality-of-life improvements:

• Better Zoom: Switched to SUPER + CTRL + scroll for a more natural and smooth zooming experience.
• tmux Resilience: Simplified the tmux keybind to use new-session -A -s Work. This attaches to an existing session if available instead of failing or duplicating.

Pull request overview

Adds mouse-wheel bindings to make Hyprland cursor zoom easier to use via SUPER+CTRL+scroll, with supporting input settings for scroll bind handling.

Changes:

• Add SUPER+CTRL mouse wheel bindings intended to control cursor zoom.
• Configure binds.scroll_event_delay to change how mouse wheel bind events are processed.

mouse_up is currently bound to “Reset zoom” (sets cursor:zoom_factor to 1). With SUPER+CTRL+scroll this makes one scroll direction always reset instead of zooming out, which doesn’t match the “natural zoom with scroll” intent and is inconsistent with other scroll binds (e.g. workspace forward/back). Consider changing the mouse_up binding to decrement cursor:zoom_factor (with a floor at 1), and keep reset on an explicit keybind (like the existing SUPER+CTRL+ALT+Z).

Suggested change

	bindd = SUPER CTRL, mouse_up, Reset zoom, exec, hyprctl keyword cursor:zoom_factor 1
	bindd = SUPER CTRL, mouse_up, Zoom out, exec, hyprctl keyword cursor:zoom_factor $(hyprctl getoption cursor:zoom_factor -j | jq '.float - 1 | if . < 1 then 1 else . end')

Setting binds.scroll_event_delay = 0 affects all mouse-wheel bindings globally (e.g. SUPER+scroll workspace switching and group navigation), not just the new zoom binds. This can make wheel-driven actions fire extremely rapidly and overshoot. Consider using a small non-zero delay tuned for usability, or documenting the tradeoff here since it changes behavior repo-wide.

Suggested change

	binds {
	binds {
	# NOTE: This value applies globally to all mouse-wheel bindings (e.g. SUPER+scroll
	# for workspace switching and group navigation). A value of 0 makes wheel actions
	# fire as fast as the hardware reports events, which can cause overshooting.
	# Increase this to a small non-zero value if scroll-driven actions feel too fast.
