Switch Durable Object migrations to SQLite

Replace wrangler migration entries from `new_classes` to `new_sqlite_classes` across fixtures and READMEs and add a changeset documenting that partyserver now relies on SQLite-backed Durable Objects (synchronous storage). Update use-socket logic to track option changes while disabled, ensure correct socket creation/cleanup on re-enable and StrictMode/HMR, and always connect replacement sockets. Expand tests in partysocket to cover these re-enable, token-refresh, cleanup, and wire-level scenarios. Breaking: Durable Object namespaces must use `new_sqlite_classes` when deployed.

+Uses `ctx.storage.kv` (synchronous KV) internally to persist `Server.name` across cold starts. This requires SQLite-backed Durable Objects, so you must use `new_sqlite_classes` instead of `new_classes` in your wrangler configuration's `migrations` field.
+
+**Breaking:** If your Durable Object namespace still uses `new_classes`, you will see the following runtime error:
+
+> The storage.kv (synchronous KV) API is only available for SQLite-backed Durable Objects, but this object's namespace is not declared to use SQLite. You can use the older, asynchronous interface via methods of `storage` itself (e.g. `storage.get()`). Alternatively, to enable SQLite, change `new_classes` to `new_sqlite_classes` within the 'migrations' field in your wrangler.jsonc or wrangler.toml file.
+
+**Note:** This migration cannot be reversed once deployed to production.
