Apparently if tsbuildinfo exists but the output itself is deleted, then nothing will be reemitted? At least that's what seems to happen with our build setup Co-authored-by: Copilot <copilot@github.com>

Pull request overview
This PR adjusts the extension rebuild workflow in the VS Code build system to ensure extensions are re-emitted correctly during local development when outputs have been deleted but incremental build metadata remains.
Changes:
- Add deletion of the relevant
*.tsbuildinfofile when cleaning an extension’sout/folder. - Convert the extension clean task to an async task to sequence
out/removal and build-info cleanup.

| build/gulpfile.extensions.ts | Ensures extension clean removes both out/ and the corresponding .tsbuildinfo to prevent incremental builds from skipping emits. |

Seems like if a tsbuildinfo file exists but the output itself is deleted, then nothing will be reemitted by tsgo? At least that's what seems to happen with our build scripts for local development
cc @connor4312 See if this fixes the issue you were seeing. I couldn't repo it initially because I was always trying clean builds
