Async conversion
convert host to async non-send
demonstrate operation with existing lex-hello example
consider converting extension's SysCtx to a typed context bag
align fn atom and macros on both sides with new design. No global state.
alternate extension mechanism
The Macro extension needs to be in the same compilation unit as the interpreter because the interpreter needs to proactively access its datastructures (in particular, it needs to generate MacTree from TokTree)
Ideally, it should reuse orchid-extension for message routing and decoding.
orchid-host accepts extensions as impl ExtensionPort
Preprocessor extension
Must figure out how preprocessor can both be a System and referenced in the interpreter
Must actually write macro system as recorded in note
At this point swappable preprocessors aren't a target because interaction with module system sounds complicated
Check if any of this needs interpreter, if so, start with that
