[BUG] Mojo LSP starts parsing multiple times in Google's Antigravity

Actual behavior

Sometimes the Mojo vscode extension/language server appears to be parsing the files multiple times concurrently in Google's Antigravity which causes the language server to never finish and just hangs forever. **Note I have not tested or reproduced this issue with VSCode, but antigravity is a modified fork of vscode so the extension is the same extension.

You can see in the image how the document is being parsed multiple times. I've killed the background parsing processes repeatedly but they keep starting up when I save my file. I'm not sure if this is a bug with the Mojo language server/extension, or if this is an issue with Google's Antigravity. Restarting the LSP Server works to resolve the issue, but it happens frequently enough to become an issue. Sometimes I repeatedly press Ctrl. S to save quickly which might increase the likelihood of the issue, though I can't be certain.

Expected behavior

The language server should parse my documents (when it does successfully parse through the handful of documents I have, it does so in a matter of seconds) It should be quickly parsing each document once and not hanging forever causing syntax highlighting and errors to never resolve.

Steps to reproduce

• Open some mojo files in Google's Antigravity
• Make a change to one of the files
• Press Ctrl S (possibly repeatedly multiple times)
• Notice that often the Parsing Document notification on the status bar at the bottom hangs at parsing the current file and does not resolve. Clicking on it shows the list of files being parsed and often it shows the same file being parsed multiple times and never finishes.

Start by reproducing the issue with the Mojo VS Code extension in Google's Antigravity: open Mojo files, save one repeatedly, and inspect the Parsing Document status and concurrent processes. Compare behavior with VS Code if possible to determine whether the extension or Antigravity is responsible. Done means each document is parsed once, parsing finishes, and syntax highlighting and errors resolve.
