Release: v2.56.1 (#2097)

* Logo (Builtin): drop opak

Ref: #1070

* Swap (Windows): adds `K32GetPerformanceInfo` fallback

* Platform (Windows): fixes if checks

* Platform (Windows): adds a null check

* Packages (Windows): improves performance for directory enumeration

* Util (Windows): fixes / adds a new Unicode conversion function

* Packaging: update debian stuff [ci skip]

* IO (Windows): enhances `openat`

* CPU: adds option `tempSensor`

* CPU (macOS): supports `tempSensor`

* CPU (Windows): supports `tempSensor`

* CPU (Linux): supports `tempSensor`

* CPU (FreeBSD): supports `tempSensor`

* CPU (NetBSD): supports `tempSensor`

* CPU (OpenBSD): supports `tempSensor`

* CPU (Linux): prevents variables from integer overflow

* GPU (Linux): add comments

* CPU (SunOS): supports `tempSensor`

* Doc: clarifies that we supports illumos only

* JsonSchema: documents `cpu.tempSensor`

Fixes #2073

* CPUCache (macOS): fixes cache line size detection

* CPU(Linux): Fix build on GNU.

* Chore: refines usage of `PATH_MAX`

* DisplayServer (Linux): upgrades kde-output-device-v2 wayland protocol files (again)

Fixes #2093

* Logo (Builtin): adds gxde logo (#2094)

* add gxde-logo

* add gxdeos

* add gxdeos

* add gxdeos

* Release: v2.56.1

* Memory (macOS): uses `hw.memsize_usable`

* Chore (Windows): Standardize windows header casing. (#2096) [ci skip]

Followup to 0b6ca15.

* IO (Windows): removes unneeded null terminator appending

* CPU (SunOS): adds `const` for consistancy

* Host (macOS): prefers `hw.product` than `hw.model`

... because `HW_MODEL` is deprecated

* Doc: update changelog

* Memory (macOS): Refines Memory usage detection on macOS to match Activity Monitor more closely

* Packages (Windows): fixes possible UB

Reported by Github Copilot

* JsonSchema: refines comments [ci skip]
