fix(lsp): send workspace folders during initialization

[bajrangCoder]

Pass the resolved workspace root through initialize.workspaceFolders so language servers such as ty can discover project configuration and Python virtual environments.

[greptile-apps]

Greptile Summary

The PR completes the LSP workspace-root initialization fix by passing resolved roots in initialize.workspaceFolders for document-scoped clients while preserving dynamic folder registration for shared workspace clients.

• Adds workspaceFolders capability and initialization payload support.
• Derives a readable workspace name from the resolved root URI.
• Makes root logging explicit after initialization.

Confidence Score: 5/5

The PR appears safe to merge.

No blocking failure remains.
