feat: Endpoint.update programmable sideeffects

[ntucker]

Motivation

Iterating toward #760

• Define programmable update in endpoint
• Improve function signature

Solution

We maintain working on raw reducer state, however we introduce improvements on the update method itself being much more straightforward and easy to define correctly.

• two degree function
• map key -> update function

const createUser = new Endpoint(postToUserFunction, {
  schema: User,
  update: (newUserId: string)  => {
    const updates = {
      [userList.key()]: (users = []) => [newUserId, ...users],
      [userList.key({ sortBy: 'createdAt' })]: (users = [], { sortBy }) => {
        const ret = [newUserId, ...users];
        ret.sortBy(sortBy);
        return ret;
      },
    ];
    if (newUser.isAdmin) {
      updates[userList.key({ admin: true })] = (users = []) => [newUserId, ...users];
    }
    return updates;
  },
});

Legacy plan

This PR

• Maintain previous updaters in reducer
• add update method to actions
• introduce usage in useFetcher found in experimental

Stage 2

• Make previous useFetcher() method transform into new update meta

Stage 3

• Stop supporting old update meta by removal from reducer
