Fix colorscheme tests with proper color assertions and variable scoping

- Fixed variable scoping issues in tests by defining colors in Before blocks
- Updated color assertions to match actual colorscheme values
- Improved TypeScript syntax highlighting tests
- Fixed diff mode and search highlighting tests
- Ensured both oscura and oscura-dusk colorschemes load correctly
