[ECO-1562] Begin preliminary struct architecture

[alnoki]

Description

1. Escape emoji words globally since they will likely occur in other contexts
2. Refactor package layout for emojicoin_dot_fun::emojicoin_dot_fun structure
3. Escape a flake warning
4. Add a stub to the supported emoji set to enable [ECO-1556] Enforce valid emojis in a Move contract #5 (comment)
5. Add struct layout:

The registry is stubbed to enable #5 (comment).

Markets are also stubbed as an object, to enable coin factory bytecode operations.

Struct layout:

RegistryAddress is stored under @emojicoin_dot_fun as a means for indexing: a view function can allow an offchain element to determine the address of the registry object by checking the RegistryAddress.

The Registry is an object complete with an extend_ref, which allows it to publish markets at deterministic object addresses. New markets may be published via object::create_named_object for the Registry.extend_ref as the signer, and the emoji bytes of the market as a seed. This will allow for deterministic passing of type arguments during market init calls via public entry functions, since the expected object address can be determined offchain, then packed into an SDK type argument call that will correspond to types published from coin factory bytecode stored onchain.

That is, the Emojicoin and EmojicoinLP types will be published under the Market.extend_ref signer, which is a function of the Registry.extend_ref address and the emoji_bytes for the market

Testing

From src/move:

git ls-files | entr -c aptos move compile --dev

Looks good to me! Just the one comment I made, but doesn't make much of a difference
