Bitcoin Core PR #34911 gates deprecated mempool RPC keys
Bitcoin Core PR #34911 removes the deprecated `fullrbf` and `bip125-replaceable` keys from mempool RPC responses, keeping them only when explicitly requested via `-deprecatedrpc`.
Mechanically, this continues the v29 deprecation path where the `fullrbf` argument was removed from default behavior. The effect is a smaller default RPC surface for obsolete RBF/BIP-125 signaling and less ambiguity in mempool response parsing.
Caveat: any node tooling, scripts, or middleware that assumes these keys are always present may break unless it opts in with `-deprecatedrpc`.
