Distinguish between agent conversation model update types

+## Description
+
+The "Runs" agent management view rebuilds its entire card list whenever any conversation's status changes. Most of those events are visually no-ops (re-emitted statuses or status changes that don't cross the active filter), but subscribers can't tell because the event carries no detail.
+
+This PR is the first of two and only changes the shape of the conversation status update event. Subscribers continue to behave exactly as before. The follow-up PR uses the new payload to skip rebuilds in the common cases.
+
+Concretely:
+- `BlocklistAIHistoryEvent::UpdatedConversationStatus` now carries the previous and new `ConversationStatus`. Restoration events report `prev_status: None` since restoration doesn't change the underlying status.
+- `AgentConversationsModelEvent::ConversationUpdated` now carries a `conversation_id` and a typed `ConversationUpdateKind` of either `Restored` or `StatusSet { prev_filter, new_filter }`. Filter buckets are precomputed at emission time so subscribers don't have to recompute membership.
+- A small helper `conversation_status_filter` maps `ConversationStatus` to its `StatusFilter` bucket.
+- All existing subscribers were updated to the new event shape with `{ .. }` patterns and ignore the new fields. The variant is annotated with `#[allow(dead_code)]` until the follow-up PR lands.
+
+## Testing
+
+- Added/updated four unit tests on the model: `Restored` emission, `StatusSet` transitions across filter buckets, same-bucket re-emission, and the `ConversationStatus → StatusFilter` mapping.
+- Existing `agent_conversations_model` tests pass against the new payload.
+- `cargo check`, `cargo fmt`, `cargo clippy` all clean.
+- No user-visible behavior change, so no manual smoke test needed.
+
+## Server API dependencies
+
+No server dependencies — purely client-side event-shape changes.
+
+## Agent Mode
+
+- [x] Warp Agent Mode - This PR was created via Warp's AI Agent Mode
+
+## Changelog Entries for Stable
+
+(No changelog entry — no user-visible behavior change. The follow-up PR carries the changelog entry.)
