Update gitignore to include cursor/extensions (#2444)

* Resolves: None

Signed-off-by: Aviv Turgeman <aturgema@redhat.com>

* Address review: narrow .vscode/ ignore to launch.json only

The blanket .vscode/ rule would prevent future changes to shared
files (extensions.json, settings.json, tasks.json). Target only
launch.json which is the local-only config.
