## Summary
Drafts were showing up in the Home Inbox **All** view, mixed in with
messages and reminders (reported in `#buzz-bugs`). Drafts are private
composer state, not inbox activity — they now appear only under the
dedicated **Drafts** filter.
## Changes
- **`inboxListRows.ts`** — drop the `draft` row variant from
`buildInboxListRows`; the mixed view builds only `inbox` + `reminder`
rows.
- **`InboxListPane.tsx`** — remove the draft branch of the All-view
render path; `PersonalItemRow` now renders reminders only.
- **`useHomePersonalInbox.ts`** — stop enabling draft selection (and its
root-status relay probing) for the mixed view; draft selection is scoped
to the Drafts filter.
- Drafts filter behavior is unchanged: the filter badge count,
`DraftsPanel` list, and `DraftDetailPane` all still work.
## Testing
- `pnpm test` (desktop unit suite): 3697 passed, 0 failed.
- `pnpm exec biome check src/features/home tests`: clean.
- Updated `inboxListRows.test.mjs` for the two-variant row model.
- Updated the e2e test (`channels.spec.ts`) to assert All never lists
drafts and that the draft is still reachable under the Drafts filter.
- Added `drafts-all-fix-screenshots.spec.ts` capturing both states
(screenshots below).
### All view — draft is gone, messages/reminders unaffected

### Drafts filter — the draft is still listed and editable
