Do nuqs support hash mode?

Like URL:

/chat#session=2007125b-5d59-4770-9bd4-c7c3668ff008&topic=ABCD

instead of

/chat?session=2007125b-5d59-4770-9bd4-c7c3668ff008&topic=ABCD

It's useful for the local first app.

It currently doesn't, only search params.

Some issues with hash mode to consider:

• Hash is never sent to the server, this makes it incompatible with shallow: false
• The URL hash does not have a structure, unlike the query string with the URLSearchParams interface. While it could be adapted (essentially replacing ? with #), Next.js would probably not re-render when the hash is updated (TBC).

Note that search params updates are local-first (not sent to the server) by default in nuqs.

Hash is never sent to the server

this is the reason why using hash params. For exmaple, we save data in user's browser storage like localStorage and indexedDB. Sending this type prarams to server is meanless. So shallow maybe not need to be considered?

Next.js would probably not re-render when the hash is updated (TBC).

what this will casue? change the hash url not make state update value?
