Fix exploration and battle system state management bugs

- Fixed exploration bug: prevent multiple \!explore when encounter is active
- Fixed battle bug: prevent starting multiple battles from exploration encounters
- Enforced exploration encounter workflow: must choose fight/capture/flee before exploring again
- Fixed \!gym challenge to use player's current location instead of requiring location parameter
- Added proper state management to prevent race conditions
- Improved user experience with clear error messages for active encounters
