Studio package-create UX dogfood follow-ups (2026-07 browser walkthrough)

[os-zhuang]

Tracking issue for the Studio package create / edit / view dogfood walkthrough (2026-07). Records what shipped and the remaining minor items.

Shipped

• ✅ Duplicate package id silently overwrites → POST /packages now 409s on an existing id (with overwrite escape hatch). framework#2971
• ✅ Two divergent create UIs / id-regex split → unified onto the spec-driven PackageFormDialog (create/edit/view in a modal, form generated from ManifestSchema). feat(studio): spec-driven package create/edit/view form in a modal #2535
• ✅ Dead code cleanup from the form migration. chore(studio): remove dead code left by the package spec-form migration #2540
• ✅ PATCH /packages/:id route was never mounted (edit silently 405'd) → route registered. framework#2995
• ✅ Builder top-bar name stale after rename → switcher refetches on objectui:packages-changed. fix(studio): refresh builder top-bar name after a package rename #2554
• ✅ Forced "New Object" modal on every package create → auto-open removed; the empty-state panel now carries an opt-in "New object" CTA (hidden on read-only packages). fix(studio): stop force-opening the new-object dialog on empty packages #2569
• ✅ Mixed-locale rendering in one session → metadata-admin now follows the live app language via useMetadataLocale() (was reading navigator.language only), so Studio tracks the LocaleSwitcher instead of diverging from the console. fix(metadata-admin): follow the live app locale, not just navigator.language #2602
• ✅ (future-proof) SDK client.packages.install() overwrite → added to the options bag, symmetric with the 409 endpoint. framework#3007

All follow-ups shipped — closing.

Environmental (not app bugs): the in-app preview browser intermittently chrome-errord on direct /studio navigation.
