🔧 fix: Fix rampant pings and rate limiting

- Skips idle connection checks in `getMCPManager` to avoid unnecessary pings.
- Introduces a skipOAuthTimeout flag during initial connection to prevent timeouts during server discovery.
- Uses a lightweight connection state check instead of ping to avoid rate limits.
- Prevents refetch spam and rate limit errors when checking connection status.
- Fixes an issue where the server connection was not being disconnected.
