[Bug] Extension Fails with Spaces in Project Directory Path

Bug Report:

Bug Description
Claude Code VS Code extension hangs indefinitely ("Unravelling..." state) when the workspace directory path contains spaces. Extension works correctly only when all directory names in the path have no spaces.

Current Workaround
Opening Claude via VS Code's integrated terminal (claude command) works correctly regardless of spaces in directory path.

Expected Behavior
Extension should properly escape/quote directory paths with spaces, matching the behavior of the CLI.

Environment

• Platform: darwin (macOS)
• VS Code Extension Version: 2.0.0
• Claude Code CLI Version: 2.0.1
• Terminal: vscode
• Feedback ID: 20b18886-3527-4632-a325-0e758b93071e

Steps to Reproduce

1. Open VS Code in a directory with spaces in the path (e.g., /Users/theo/My Projects/test)
2. Attempt to use Claude Code extension (Cmd+Shift+/)
3. First query may work, but subsequent queries hang on "Unravelling..." indefinitely
4. Extension becomes unresponsive

Impact
Forces users to rely on integrated terminal instead of extension features, significantly reducing UX quality for projects with spaces in paths.
