fix: keep parse-on-save scans quiet on config errors

[gcomneno]

Summary

• Skip automatic parse-on-save scans when the BitBake settings are not sane.
• Keep manually invoked commands unchanged, so they can still focus the BitBake view on configuration errors.

Testing

• npm run compile
• npm run lint -- client/src/extension.ts
• git diff --check

Fixes #525.

That's a better approach! Thanks! Now I simplified the patch so the on-save handler now returns early when the BitBake settings are not sane, without adding parameters to the command handlers and perform other stuff. Manual commands still keep their existing behavior. :)

I tested the behavior which is perfect.
A minor remark on the code
