Improve gt mol help and add gt formulas command

- Rewrote gt mol help to focus on agent operations (YOUR hook, YOUR work)
- Removed misleading "use bd mol pour" guidance (gt sling handles this)
- Added gt formulas command as convenience wrapper for bd formula list
- Agents no longer need to know about bd for common workflow operations
