mongo — ledger

v0.1.1

• fidelity fix (MEDIUM): added check_document_exists(collection, target) -> bool (count_documents(target, limit=1) > 0). It existed only in the talos origin and was not carried over; the talos caller (local.py:157) relies on it.
• param rename (breaking): update_document / find_one_and_update / find_one_and_replace now take upsert= (was do_upsert=), standardizing on the motor name. Consumers passing do_upsert= must switch to upsert= on migration; the talos caller already uses upsert= and is now correct as-is.
• README install line corrected to the git+ssh form (was git+https).
• close() is synchronous (motor's close is sync) — not awaited.
• get_document_hashmap / get_document_fields skip docs missing the key (was an unguarded doc[key] that swallowed a KeyError to {}/[]).

v0.1.0

• initial: async MongoDB wrapper over motor; wrapped methods log-and-swallow to safe defaults; raw .collection() / db[name] escape hatch raises.
