Improve code quality grep checks

[out-of-phaze]

Description of changes

• Adds a check for the tag var in code, expanding it from just checking in maps.
• Removes unnecessary usage of the tag var.
• Replaces all current uses of direct_output with specialized helpers, in preparation for allowing drop-in optional replacement for downstreams that want to opt into things like rust-g to improve performance.
• Improves a lot of our grep checks to reduce false positives.
• Removes 15 in world loops, either deleting them entirely because they're dead code, or replacing them with other lists.
• Fixes redundant code in supply pack setup. This just got thrown in because eh, why not.
