Subject: Remove Splash syntax highlighter dependency

Splash only highlights Swift, leaving every other language unhighlighted.
Drop the dependency entirely and render file contents as plain text until a
broader-coverage highlighter is adopted.

- Remove `import Splash` and the Splash-backed theming in FileTreeView
- Simplify CodeSyntaxHighlighter to emit plain attributed text
- Remove the Splash SwiftPM package reference and product dependency
