fix: improve file search to handle filenames with spaces

- Enhanced searchWorkspaceFiles function to create multiple search string variations
- Files with spaces now appear in autocomplete without needing to be opened first
- Added comprehensive unit tests for the fix

Fixes #7272

+# Test File with Spaces
+
+This is a test file to reproduce the issue where files with spaces in their names don't appear in the @ autocomplete suggestions unless they are opened in VS Code first.
+
+## Issue Details
+
+- Files with spaces should appear in autocomplete
+- Currently they only appear after being opened in a tab
+- This is a regression from previous fixes
+
+## Test Content
+
+This file should be discoverable when typing `@test` in the Roo Code chat input.
