This library claims to be a Hammer texture browser for Source 1, but this build only contains compiler-generated metadata. There is no runtime code, systems, or assets, so it does nothing in game.
Adds a Hammer texture browser dock to the editor. It lists material assets with thumbnails, filters by name and usage, shows texture sizes, and lets you mark, replace, or open materials. It reuses an existing dock or creates one next to the Asset Browser and calls into Hammer map editor methods by reflection.
Unit tests for the library. They init Sandbox.TestAppSystem for the test run, then create a Scene, push it, spawn a GameObject, and assert the scene directory reports one object.
