Subject: [PATCH 2/7] Implement stages 1 & 2: adopt workspaceFolders instead of
 deprecated RootPath/RootUri

- Stage 1: Use workspaceFolders[0].Uri instead of deprecated RootPath/RootUri
- Stage 2: Probe all workspace folders for F# code and select first one with projects
- Maintain backward compatibility with fallback to RootUri/RootPath when workspaceFolders not available
- Add logging for workspace folder selection

Subject: [PATCH 3/7] Add comprehensive tests for workspaceFolders
 initialization

- Test single workspace folder selection
- Test multiple workspace folders with F# code detection
- Test backward compatibility with RootUri and RootPath
- Test empty WorkspaceFolders array fallback
- All tests verify proper initialization with new lookup mechanism

Subject: [PATCH 5/7] Fix InitTest failure by respecting AutomaticWorkspaceInit
 setting

- Only probe workspace folders for F# code when AutomaticWorkspaceInit is true
- When AutomaticWorkspaceInit is false, use first workspace folder directly
- Maintains backward compatibility with existing tests
- Formatted with fantomas
