bug: symf not killed when workspace closes or VS Code quits

[toolmantim]

Version

0.16.0

Describe the bug

If a workspace kicks off symf indexing and you close the workspace window, or even quit VS Code altogether, it continues to index in the background. The only way to stop it is to force kill the process in Activity Monitor.

To recreate:

• Open activity monitor, filtered by 'smyf'
• Open a large repository (e.g. chromium)
• See symf indexing
• Close the workspace and see symf still indexing
• Quit VS Code and see symf still indexing

Expected behavior

symf is terminated when a workspace is closed and when VS Code quits
