Subject: [PATCH] fix(web): decode JSON-stringified ajs_anonymous_id from
 localStorage (#196) analytics.js stores ajs_anonymous_id as a JSON-encoded
 string, wrapping the UUID in surrounding double-quote characters.
 getExistingAnonymousId() read the raw value without decoding, causing
 identity mismatches between the JS and Flutter SDKs.
