Lets a particle's creator delete their own message from the TopBar dropdown. Other viewers see a "This particle was deleted" tombstone in place and playback auto-advances after ~2s, keeping indices stable for concurrent watchers. - Add optional deleted_at / deleted_by_human_id to non-container particle variants and isParticleDeleted helper. - Add softDeleteParticle Firestore helper. - New DeleteParticleOverlay confirmation and DeletedParticleView tombstone. - Hide reactions (bar + 1-7 keybinding) on tombstoned particles. - Show "Deleted particle" + Trash2 icon in the stream list preview.
