Critical bugs fixed:
- $derived(() => {}) stored the function itself; uuid/api_key were always
undefined so verification never fired. Fixed to $derived.by(() => {}).
- novi_verifying pre-initialized to true (flash prevention) was also used as
the concurrency guard — guard saw it as in-flight and exited immediately,
leaving the spinner stuck forever. Split into separate verify_in_flight flag.
- $idaa_loc reads in dedupe snapshot (outside untrack) subscribed the effect
to idaa_loc writes, causing needless re-runs post-verification.
- Rate limit was not UUID-aware: 429 on one UUID blocked impersonation
(new UUID). TTL and rate-limit guards now both bypass when UUID changes.
Also includes: store defaults for novi_verified_ts + novi_rate_limited_until,
docs update, iframe template g_uuid param (prior agent changes).
