🦩 🔴 async-nats/nats.rs contains no auth_url_callback fork feature; sync workflow merges upstream unconditionally

In the Sync step of the sync job in .github/workflows/sync-upstream.yml, added a post-merge verification gate that greps the repo (.rs files) for auth_url_callback after git merge --no-ff --no-edit upstream/main succeeds; if the string is absent, the workflow logs an ::error::, resets the branch back to origin/main, deletes the local sync branch, and exits with failure instead of proceeding to push/PR. Added a new Build and test fork feature gate step running cargo check --workspace --all-features and cargo test --workspace --all-features -- auth_url_callback scoped to run only when the marker is present, and moved the git push/gh pr create into a final Push branch and open PR step so the PR is only opened after both the presence check and the build/test gate pass. This is a heuristic, grep-based proxy for "the fork feature still exists/compiles" since I have no visibility into the actual source files, function names, or test names in this repo — a complete fix would require knowing the real file(s)/API surface implementing auth_url_callback (e.g., a specific struct/trait method in async-nats or nats.rs) so the check and test invocation target it precisely rather than a raw string grep, and would require confirming cargo test ... -- auth_url_callback actually maps to real test names in this crate.

In .github/workflows/sync-upstream.yml around line 30, review and complete this code-review fix: async-nats/nats.rs contains no auth_url_callback fork feature; sync workflow merges upstream unconditionally.
What the draft fix changed: In the `Sync` step of the `sync` job in `.github/workflows/sync-upstream.yml`, added a post-merge verification gate that greps the repo (`.rs` files) for `auth_url_callback` after `git merge --no-ff --no-edit upstream/main` succeeds; if the string is absent, the workflow logs an `::error::`, resets the branch back to `origin/main`, deletes the local sync branch, and exits with failure instead of proceeding to push/PR. Added a new `Build and test fork feature gate` step running `cargo check --workspace --all-features` and `cargo test --workspace --all-features -- auth_url_callback` scoped to run only when the marker is present, and moved the `git push`/`gh pr create` into a final `Push branch and open PR` step so the PR is only opened after both the presence check and the build/test gate pass. This is a heuristic, grep-based proxy for "the fork feature still exists/compiles" since I have no visibility into the actual source files, function names, or test names in this repo — a complete fix would require knowing the real file(s)/API surface implementing `auth_url_callback` (e.g., a specific struct/trait method in `async-nats` or `nats.rs`) so the check and test invocation target it precisely rather than a raw string grep, and would require confirming `cargo test ... -- auth_url_callback` actually maps to real test names in this crate.
The fix is LOW CONFIDENCE — verify it is correct and finish whatever it left incomplete.

🦩 🔴 handle_auth_error / auth_url_callback: reconnect loop silently reuses server list on parse failure without dropping obsolete auth state

In handle_auth_error, the finding is about the parse-failure/no-retry path leaving the connector looping with stale server state and only a generic error surfacing. The primary lever available in this function without inventing new fields is to ensure callers no longer silently keep looping on Ok(false). I did not add new state-reset logic inside handle_auth_error itself (there is no "last known-good" snapshot field to restore from, and inventing one would risk correctness), but I fixed the caller side (connect(), see item 2) so that a handle_auth_error returning false after a parse failure now terminates the loop with a real, propagated ConnectError instead of silently falling through forever. This directly resolves the "inconsistent retry state" symptom (infinite fall-through) but does not add explicit rollback of self.servers to a snapshot, since no such snapshot exists in the current struct — a complete fix would require adding a last_known_good_servers: Vec<(ServerAddr, usize)> field and restoring it here, which is a larger structural change I flag as a residual risk.

🦩 🟠 connect() error loop discards MaxReconnects/AuthorizationViolation errors as fire-and-forget events instead of returning them

In Connector::connect(), the ConnectErrorKind::AuthorizationViolation arm and the other (catch-all) arm previously fell through to loop again indefinitely after only doing try_send(...).ok(). Both arms now return Err(error) (propagating the original ConnectError, preserving its source/kind) after emitting the same tracing/event side effects, so a genuinely fatal error (e.g., bad TLS config, or an auth violation with no working callback) is returned to the caller instead of spin-looping forever. This also resolves finding 1's "silently reuses server list" symptom, since the loop can no longer fall through in the parse-failure case.

Verify the change is correct and complete; do not refactor unrelated code.
