- Default app landing changed from Pantry to Recipes tab
- Pre-fetch inventory on app mount so Find tab has data immediately
- Reorder recipe sub-tabs: Saved > Build Your Own > Community > Find > Browse
- Default active sub-tab changed to Saved
- Auto-redirect from Saved to Build Your Own when saved list is empty
- Add freeform custom ingredient input: typing a non-pantry item now shows
"Use X anyway" button so users aren't blocked on unknown ingredients
