Python decoder side of the write receipt (spec: contracts/cultnet/interop/write-receipt.md). Stacked on #64; the diff is only the Python runtime.

• parse_message validates cultnet.write_admitted.v0 and cultnet.error.v1 as closed schemas; error.v1 shares the v0 shape rules plus required messageId and limit_reached; v0 stays closed.
• write_content_hash, hello_advertises_write_receipts, CULTNET_ERROR_V1_CODES, CULTNET_WRITE_RECEIPT_MESSAGE_VERSIONS; hello(supported_message_versions=...).
• tests/test_write_receipt.py replays contentHash (4), wire (7, decode + byte-identical re-encode), schemaInvalid (7).
• Not done, by design: scenarios (client WriteTracker; python has no write client), dedupe and blankFields (server rules; no receipt server in cultnet-py). Interop schemas are read in place from contracts/cultnet/interop.
• Mutants (mutmut, messages.py): the 164 in the new functions, 163 caught; 1 survivor is equivalent (use_bin_type is msgpack's default).
