Tom Brow ff6ab96e42 fix(mobile): drop the # from Solo chat names in push notifications (#8955)
## Summary

Push notifications for Solo chats were titled like channels (`#Trip
planning`). The iOS notification extension added `#` to every stream and
forum conversation name, but the app presents Solo chats as personal
chats, not channels.

- `BuzzPushCachedChannel` gains optional `isSolo` and `creatorPubkey`,
derived from relay kind 39000 metadata. `isSolo` uses the same rule as
the app's `Channel.isSolo`: a private stream whose NIP-CL labels (every
`t` after the leading type) include `buzz.solo`. `creatorPubkey` is the
relay-authored `P` tag.
- The resolver uses the bare channel name only for the viewer's own Solo
chats (matching `Channel.isPersonalChat`, which requires `createdBy ==
viewer`). Someone else's Solo chat, and every other channel, keeps
`#name`.
- `isSolo` is optional, so existing App Group caches still decode.
Entries cached before this change have no flag and keep the `#` until
their metadata is refreshed.

## Validation

- `swift test --package-path mobile/ios/BuzzPushKit`: 104 XCTest and 66
Swift Testing tests pass, including two new ones:
- `testOnlyOwnSoloChatConversationNameDropsChannelHash`: a fresh Solo
metadata fetch yields `Trip planning` when the viewer created the chat
and `#Trip planning` when someone else did. Removing the creator check
makes it fail.
- `soloClassification`: only private `stream` channels labelled
`buzz.solo` are marked Solo (open, forum, label-only and unlabelled
private streams are not), and the `P` creator is cached lowercased.
- Live relay check: a local relay with synthetic identities, a Solo chat
("Weekend plans") and a private channel ("design-review"), each with a
second member who posts. The production `BuzzPushNotificationResolver`
(the code the notification extension calls), run against relay-built
kind 39000 metadata, gives:

  | | Solo chat | Channel |
  |---|---|---|
  | main | `#Weekend plans` | `#design-review` |
  | this PR | `Weekend plans` | `#design-review` |

- Not covered: a banner rendered by the notification extension. `simctl
push` delivers to the simulator as a local notification and never
launches the extension, and a real APNs push needs credentials this
machine doesn't have.

## Follow-up after merge

Merging on the live relay check above. Still to do once a dogfood build
includes this change:

- [ ] On-device push check on a BLIMP: a Solo chat push shows the bare
name and a channel push keeps `#name`.
- [ ] Before/after notification screenshots.
