ace-core

Foundation layer. Defines the three codec traits that everything else builds on:

• FrameRead<'a> — zero-copy decode from a &mut &'a [u8] cursor
• FrameWrite — encode into a Writer (either &mut [u8] or BytesMut)
• Writer — sealed trait abstracting alloc and no-alloc write targets

Also provides DiagError, AddressMode, DiagnosticAddress, and the FrameIter<'a, T> lazy iterator for variable-length repeated fields.
