These Nerdfonts codepoints were removed in [3.0.0](https://www.nerdfonts.com/releases#v3.0.0):
> **Breaking 2: Material Design Icons Codepoints**
>
> The old Material Design Icon codepoints are finally dropped. Due to an historic mistake we placed them in between some asiatic glyphs, breaking that script. Since v2.3.0 the (updated and expanded) Material Design Icons have new codepoints in the 5 digit region.
>
> - Dropped codepoints `F500`… and class names `nf-mdi-*`
> - New codepoints `F0001`… and class names `nf-md-*`
> - The whole discussions are here: https://github.com/ryanoasis/nerd-fonts/issues/365
> - A translation table is available here: https://github.com/ryanoasis/nerd-fonts/issues/1059#issuecomment-1404891287
> - There are tools out there that probably can update your configuration.
For the majority of the removed symbols, it was as easy as finding the
replacement with the exact same name. For example, `f76b` (`nf-mdi-format_header_2`)
became `f026c` (`nf-md-format_header_2`).
There was one symbol that was completely removed (it was removed from
Material Design): `f5fc` (`nf-mdi-camcorder_box`). I have substituted it
with `f03d` (`nf-fa-video_camera`) which is not Material Design, but the
closest icon I could find.
Here's some example output from [nerdfix](https://github.com/loichyan/nerdfix)

Load attention and overlay pixmaps from item properties, watch the
corresponding update signals, and prefer attention artwork while an item is in
NeedsAttention state.
When an item only exports an attention movie asset, fall back to loading that
asset as a static pixbuf so the tray still shows the alert state.

Only add tray widgets after the SNI proxy has finished initializing and the
item has a valid id/category pair.
This also removes invalid items through the host teardown path, refreshes the
tray when item status changes, and avoids calling DBus methods through a null
proxy during early clicks or scroll events.

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)
