Repro for slow lsp completion

See mrmckeb/typescript-plugin-css-modules#215

Steps to reproduce

• npm i
• npm run generate (this will generate a lot of files inside src/components folder, see the generate.mjs script to tweak the number of files)
• restart TS server (just to be sure)
• open src/App.tsx and try to type console.. It will take a while for completions to show up
  • open TS server logs to see how long it takes to complete
  • for me it takes ::completionInfo: elapsed time (in milliseconds) around 8–10 seconds for each completion on 1_000 files
  • Almost all the time is spent inside Finishing updateGraphWorker: Project: …/tsconfig.json Version: 3 structureChanged: false structureIsReused:: Completely Elapsed:
• try the same thing without the plugin. console. completion shows up instantly
