…otDir

When `rootDir` was set in a project's tsconfig (e.g. `rootDir: "src"`),
tsurge-based migrations would fail because `projectRoot` was derived from
`rootDir`, causing `rootRelativePath` to be computed relative to `src/`
instead of the workspace root. This produced paths like `app/app.ts`
instead of `src/app/app.ts`, which the DevKit tree could not resolve.

Fix by overriding `info.projectRoot` to `absoluteFrom(info.program.getCurrentDirectory())`
immediately after program creation, ensuring workspace-relative paths are
used for all tree updates.
