Wallet status bridge: strict typed JSON wire, bounded channel, and
no-mutation status surface. Includes the wallet_status_json fuzzer
with a seed corpus (duplicate method keys, escaped duplicates,
malformed surrogates, nested duplicates, out-of-range requests,
unknown fields, and valid request/response shapes) and the
wallet_status_bridge unit suite.
Layer 3 of the reviewed Glove wallet-status stack; status-only,
disabled by default, and no capability advertisement.
Validation: dev CTest, ASan/UBSan, TSan, and libFuzzer 10,000 units
on the final stacked tree (see workflow184 layer records).
