   Includes:

   • #36230
   • #36297
2. rpc: Correct OpenRPC default metadata

   Correct six argument metadata entries that produce misleading or invalid
   OpenRPC defaults.
   
   The getdeploymentinfo blockhash fallback and four sighashtype fallbacks
   describe how omitted arguments are resolved. They are not literal values
   accepted by the RPCs, so mark them as DefaultHint values.
   
   The send include_watching option is boolean, but its string default makes
   the generated schema internally inconsistent. Use a boolean value,
   matching the analogous sendall option.
   
   Runtime behavior is unchanged.

   LLM Linter (✨ experimental)

   Possible places where named args for integral literals may be used (e.g. func(x, /*named_arg=*/0) in C++, and func(x, named_arg=0) in Python):

   • Parse(descriptor_str, keys, error, true) in src/wallet/walletutil.h

8. wallet: Compare descriptors by hash of canonical string

   The canonical string comparison was slow because it would compute the
   canonical string for each comparison. This can be sped up by holding the
   canonical string in memory, computed upon construction of
   WalletDescriptor. To reduce memory usage, this string is further hashed
   so that the comparison operates over the hash of the canonical string.
