Summary

Implements four issues in the fractal-bridge crate:

#55 — Similarity scoring and merge suggestions (`similarity.rs`)

levenshtein_distance() and levenshtein_normalized() — normalized similarity in [0.0, 1.0]
similarity_score(a, b) — weighted score: display_name ×0.4, shared phone in native_id ×0.5, same bridge server ×0.1
MergeSuggestion { contact_a, contact_b, score }
suggest_merges(contacts, threshold) — returns pairs above threshold sorted by descending score
DEFAULT_MERGE_THRESHOLD: f64 = 0.6
Unit tests covering identical/empty strings, above/below threshold cases

#57 — Bridge detection in room details (`room_bridge.rs`)

RoomBridgeInfo { room_id, bridge_type, bot_user_id, detected_puppets }
detect_room_bridge(room_id, member_ids) — iterates members, calls BridgeType::detect(), majority-vote determines the room bridge type; falls back to BridgeType::Native
RoomBridgeDetails { info, linked_contact }

#53 — Reply channel selector (`reply_channel.rs` + `contact.rs`)

Added preferred_channel: Option<String> to UnifiedContact
ReplyChannel { user_id, bridge_type, display_name }
ReplyChannelSelector { contact }
available_channels(contact) — maps all identities to ReplyChannel
select_channel(contact, user_id) — updates preferred_channel

#56 — Contact fusion UI model (`fusion.rs`)

ContactFusionState enum: Idle, Selecting { candidates }, Confirming { a, b, score }, Done
ContactFusionModel { state, rejected_pairs } with propose_merge(), confirm(), reject(), reset()
merge_contacts(a, b) — unions identities (deduplicated by user_id), keeps display_name and id of the contact with the most identities
Unit tests for confirm/reject flows and deduplication
