feat: add threshold support and tagmap support to variable system

Browse Source 
Introduce a `threshold` column to tag modifiers in CSV declarations,
allowing modifiers to activate only when a tag's count meets a minimum
requirement.

Implement support for "tagmap" variables (e.g., `#warrior:1;#druid:2`)
which allow for complex, multi-tag state tracking. These variables
can receive specialized tagmap modifications rather than simple
numeric additions.
