fix(about): deduplicate OpenGL GPU name variants in About page

[manascb1344]

Fixes #1814

Problem

When a system has an NVIDIA GPU, wgpu enumerates it twice:

• Via Vulkan backend: "NVIDIA GeForce RTX 3080 Ti Laptop GPU"
• Via OpenGL backend: "NVIDIA GeForce RTX 3080 Ti Laptop GPU/PCIe/SSE2"

The OpenGL variant includes a renderer suffix (/PCIe/SSE2) which causes the name-based deduplication to fail, resulting in duplicate GPU entries in Settings -> System -> About.

Solution

Add normalize_gpu_name() helper that strips OpenGL renderer suffixes (everything after /) before comparing names for deduplication. This ensures both Vulkan and OpenGL representations of the same GPU are correctly identified as duplicates.

Changes

• cosmic-settings/src/pages/system/info.rs:
  • Added normalize_gpu_name() function with doc comment
  • Modified wgpu_graphics() to use normalized names for seen_names HashSet

Testing

• cargo fmt --check passes
• cargo clippy --all-features passes (no new warnings)
• cargo test --all-features passes (3/3 tests)
• just check-features passes
• Manual testing: Verified on system with NVIDIA GPU that duplicate entries no longer appear

The commit 415e1d8 was merged to master without proper formatting, so the CI failure exists
