Supersedes the active-session "defer" guard with a real merge (review #5 — "запись делать через мерж", not skip-while-editing). writeBody no longer does delete-all + re-insert (which discarded a concurrent editor's in-flight changes on every sync). It now diffs the live body against the incoming git body at TOP-LEVEL BLOCK granularity (LCS over a canonical structural serialization) and applies only the minimal inserts/deletes: - a block a human is editing is left UNTOUCHED when git changed a DIFFERENT block; - an unchanged resync is a complete 0-op write; - Yjs CRDT-merges the minimal ops with concurrent edits. New yjs-body-merge.ts (mergeXmlFragments + cloneXmlNode + diffBlocks) is pure-Yjs and unit-tested with real Y.Docs (8 tests): identical->0 ops, edit-one-block keeps the other block instances, append/delete keep neighbours, marks survive the cross-doc clone. Crash-safety kept: the incoming doc is built before the connection opens, so a transform failure can't empty the body. Removed: the ActiveEditSessionError defer path and the now-unused CollaborationGateway.getActiveEditorCount. Honest limitation: this is a 2-way merge — for a block BOTH sides changed since the last sync, git wins (no common ancestor to decide). A full 3-way merge would need the last-synced base plumbed from the engine; the dominant cases (unchanged resync, edits to different blocks) are now lossless.
