Minor Changes

• 76312e4: JSONValue.object holds a JSONObject instead of a [String: JSONValue]. A JSONObject keeps its keys as a JS object does: integer-like keys first in ascending order, then the others in the order they were set, so JSON is written as JSON.stringify writes it. Keys are compared by UTF-16 code unit, so keys that differ only in Unicode normalization ("é" and "e\u{301}") stay apart instead of one overwriting the other. Before, they merged in pokes (row values, primary keys, merges, client IDs), and custom-query and AST hashes of such keys differed from JS. Dictionary literals, object[key], and for (key, value) in object work as before, and Row(_:) and Row.object convert both ways.

  Migration: where code builds .object(dict) from a [String: JSONValue] variable, write .object(JSONObject(dict)) or declare the variable as JSONObject. objectValue and ZeroObjectReader.object/ZeroObjectWriter.object are now JSONObject; use .dictionary where a [String: JSONValue] is needed. AST.Bound.row is a JSONObject, and AnyQuery.start, TableMutator, and LoopbackServer.put take a JSONObject as well as a dictionary.

Patch Changes

• fcc95f0: Two Zero instances of one client group in one process (the same user, storageKey, and storage, such as two windows) no longer drop each other's queries: initConnection lists every running client of the group in activeClients, as in JS, so zero-cache doesn't delete the other one. When one closes, the others send deleteClients for it once.
• 48ca692: A first poke that changes nothing after a reconnect or relaunch completes the got queries, as in JS. <= and >= filters no longer match NaN. Storage: every client sharing a database hears about a write failure, and a closed client doesn't; writes queued before a failure no longer land after it; a database busy past the busy timeout is retried by the next write instead of being a storage failure; a read failure loading the client group is reported through onStorageFailure and moves the client to memory; and the memory fallback after a failed open is shared by name in the process, like .memory.
• a548803: codegen generates Swift that compiles for any table, column, relationship, JSON field, or enumeration value name. A name that is taken, a keyword Swift doesn't allow even backticked, a member the generated code declares, or a type it uses is renamed by a documented rule, and keeps its original name in the schema, CodingKeys, and raw values. Names outside ASCII are kept where Swift allows them, enumeration values with control characters are escaped as Swift allows, and a recursive json<T>() type is JSONValue where it recurs instead of overflowing the stack.
