Auto-attach pasted GitHub PR/issue URLs in the composer (#1006)

* Auto-attach pasted GitHub PR/issue URLs in the composer Paste a GitHub PR or issue link into any composer and it shows up as an attachment pill within a debounce tick when the URL matches the workspace's remote. On the new-workspace screen, an attached PR also surfaces an inline "Check out PR #N?" hint next to the picker; one click promotes it to the checkout target through the same syncPickerPrAttachment flow the dropdown uses. Unifies the new-workspace picker and composer attachment picker on one shared GitHub search hook and cache key, so both consumers (and the auto-attach lookup) share the React Query cache. * Fix oxfmt formatting in new-workspace-screen import
