Fix stale native menu hover highlight geometry

 ### Fixed
 - Menus: stop completed provider cards and plan-utilization rows from remaining in “Refreshing…” while unrelated provider or token-cost work is still running. Thanks @Yuxin-Qiao!
+- Menu: keep native hover highlights aligned by deferring geometry-changing open-menu rebuilds until the pointer leaves the row. Thanks @Zihao-Qi!
 - Codex accounts: isolate authenticated OAuth and browser-cookie requests from shared URL caches and cookie stores, preventing one account's cached quota or identity response from appearing under another account and triggering false reset alerts (#1987, #2019). Thanks @harjothkhara!
 - Claude OAuth: honor the app's never-prompt policy in the bundled CLI and defer stale cache cleanup without touching Keychain until access is re-enabled. Thanks @Yuxin-Qiao!
 - CLI server: retain timed-out route and provider work until it actually exits, preventing repeated requests or config changes from stacking background fetches. Thanks @Yuxin-Qiao!
