Move NoteExecutionHint type from miden-protocol to miden-standards following the usage pattern established in PR 0xMiden#2257 where NoteExecutionHint was removed from NoteMetadata and is now primarily used by NetworkAccountTarget in miden-standards. Changes: - Add execution_hint.rs to miden-standards/src/note/ - Remove execution_hint.rs from miden-protocol/src/note/ - Update error message in NoteError to use literal values instead of NoteExecutionHint constants (to avoid circular dependency) - Update imports in miden-agglayer and miden-testing to use miden-standards::note::NoteExecutionHint Closes 0xMiden#2281

Introduces a standard
NetworkAccountTargetattachment for use in network transactions. It replacesNoteTag::NetworkAccount(removed in #2219) to identify notes targeted at network accounts. To create a "targeted network note", i.e. a note intended to be consumed by a network account, this attachment should be used instead of usingNoteTag::NetworkAccount.Miden node can try decoding a
NoteAttachment(accessible inNoteMetadata) into aNetworkAccountTargetto check if a note is targeted at a network account. An alternative way would be to check ifNoteAttachment::attachment_type() == NetworkAccountTarget::ATTACHMENT_TYPEand only then attempt decoding.Tagging @Mirko-von-Leipzig and @sergerad for review since this type will be used in network transactions. Please let me know if the process I described would work or if you need any additional APIs exposed, etc.
