Add pylsp-workspace-symbols to third-party plugins list

[Hanatarou]

Hi,

I've published a third-party plugin that adds workspace/symbol support to pylsp via Jedi — a feature that has been missing since 2022 (see #237, #564, #511 or similar).

Plugin: https://github.com/Hanatarou/pylsp-workspace-symbols
PyPI: https://pypi.org/project/pylsp-workspace-symbols

How it works

• Uses pylsp_experimental_capabilities to advertise workspaceSymbolProvider: true
• Uses pylsp_dispatchers to register a custom workspace/symbol handler
• Calls jedi.Project.complete_search("") and filters client-side by case-insensitive substring match
• Automatically skips noise folders (.venv, __pycache__, node_modules, etc.)

Install

pip install pylsp-workspace-symbols

Would you consider adding it to the third-party plugins section of the README?
This also serves as a working solution for users while #564 is pending merge.

Thanks!
