Austin Horstman 0a35b86e20 fix(hyprland/ipc): honor the requested instance signature
The Hyprland IPC helper cached the socket folder with the first instance
signature already appended, so later calls ignored their instanceSig argument
and always reused the first path. That made the helper violate its own API even
though most real Waybar sessions only talk to a single Hyprland instance.

Cache only the base socket directory and append the requested signature per
lookup. This fixes correctness for tests, nested or debug multi-instance
setups, and future code that needs to resolve a different signature, without
claiming support for one Waybar process managing multiple Hyprland sessions.
