Hyprland workspace reloads could stack duplicate scroll-event connections,
causing a single wheel gesture to switch multiple workspaces after repeated
config reloads. The persistent-workspaces monitor-array form also created the
monitor name instead of the configured workspace name.
Disconnect and replace the scroll handler on reinit, fix the persistent
workspace name selection, normalize urgent-window address matching, and reject
malformed workspace payloads before they corrupt the local state machine.

The window module re-entered the same shared_mutex while refreshing IPC state:
update() took the lock and then called queryActiveWorkspace(), which tried to
lock it again. That is undefined behavior for std::shared_mutex and could
manifest as a deadlock.
Remove the recursive lock path and reset the derived window state before each
IPC refresh. That keeps solo/floating/swallowing/fullscreen classes from
sticking around when the client lookup fails or a workspace becomes empty.

- Replaced pass-by-value std::string parameters with const std::string&
or std::string_view to prevent SSO overallocations.
- Refactored static mapping functions in UPower to return
std::string_view instead of constructing std::string literals, enabling
perfect cache locality.
- Optimized string concatenation in hot loops (network IPs, inhibitor
lists, sway window marks) by using std::string::append() and
pre-reserving capacity instead of overloaded operator+ which produces
temporary heap instances.
These optimizations reduce high-frequency memory churn and overall heap
fragmentation within the main rendering loops.

Hyprland IPC had fd lifecycle risks on failure/shutdown paths and used a
spin-sleep listener model.
I initialized fd state defensively, tightened connect/close/shutdown handling,
moved to blocking read with newline framing, and added RAII-style fd cleanup in
socket1 reply paths.

The keyboard-state module crashes with SIGSEGV in libinput_device_ref
when a new input device appears in /dev/input/.
Three bugs fixed:
1. Missing NULL check: tryAddDevice() calls libinput_path_add_device()
which returns NULL on failure, then immediately passes the result to
libinput_device_ref() without checking. On laptops, virtual input
devices (power buttons, lid switch, etc.) appear and disappear in
/dev/input/ triggering the hotplug handler; if libinput can't open
one of these, the NULL return causes the segfault.
2. Missing cleanup on device removal: The IN_DELETE handler erased
devices from the map without calling libinput_path_remove_device(),
leaving dangling pointers in the libinput context.
3. Thread safety: libinput_devices_ was accessed from 3 threads
(main/GTK, libinput_thread_, hotplug_thread_) without any mutex.
Fixes#4851

- Move GTK operations from IPC thread to GTK main thread in Window module
- Move GTK operations from IPC thread to GTK main thread in WindowCount module
- Move GTK style class operations from IPC thread to GTK main thread in Submap module
- Language and Workspaces modules already safe (only update internal state)

Before this, vacant tags would show with `hide-vacant` set on initial
startup, because we receive initial tag events from River before we show
the bar. In that case, we won't call `set_visible(false)` on the
respective buttons because they're not shown yet. This registers the
output status listener after we show the bar so we won't miss any
events.
