fix: license icon

Resolves #2558

🧭 Context

Firefox has issues rendering SVG filters added from a sprite via "use"/ To solve this, I added a custom icon and support for them in sprite generation.

A similar style is used in the cursor and is generally closer to the other icons on the page, so I don't think anything will change for the user

📝 Walkthrough

Walkthrough

A new custom icons asset file is created with five icon definitions, integrated into the build sprite generation script and uno.config runtime configuration, and used to remap LICENSE files to display a custom license-minified icon instead of the standard vscode-icons version.

Changes

Custom License Icon Support

Layer / File(s)	Summary
Custom icons asset definition assets/media/custom-icons.json	Five custom icons (agent-skills, tangled, vlt, a11y, license-minified) are defined as a JSON object, each entry containing SVG body markup and explicit width/height dimensions.
Build sprite generation and runtime configuration scripts/generate-file-tree-sprite.ts, uno.config.ts	The sprite generation script imports custom-icons.json and updates the collection configuration to recognise custom-* naming patterns with adjusted output paths for dev/stage/prod builds. The uno.config file imports and transforms the custom icons into the presetIcons collections format by extracting the body field from each entry.
FILE_ICONS remapping for LICENSE files app/utils/file-icons.ts	Entries in FILENAME_ICONS for LICENSE, LICENSE.md, LICENSE.txt and their lowercase variants are remapped from vscode-icons-file-type-license to custom-license-minified.
