Display variable condition values in technical badges

[mikkisguy]

Problem

Technical badges currently display variable names only (e.g., has_spell, is_main_quest) without showing the actual values or comparison operators.

This makes it harder to understand what the condition actually checks at a glance.

Scope

Parse and display variable conditions with values:

• Truthiness checks: if has_spell: → shows as truthy
• Negation: if not has_drink: → shows as falsy
• String comparisons: if alignment == "good": → alignment = "good"
• Boolean comparisons: if has_drink == True: → has_drink = True
• Numeric comparisons (already handled as stats): if gold > 100: → gold > 100

Implementation

1. Data model update:

   type VariableCondition = {
     value: string | boolean;
     operator: "==" | "!=" | "truthy" | "falsy";
   };
   
   variables?: Record<string, VariableCondition>;

2. Parser updates (apps/backend/src/services/rpy-parser.service.ts):

   • Detect bare identifiers → truthy
   • Detect not var_name → falsy
   • Detect string comparisons → extract operator and value
   • Detect explicit boolean comparisons → == True, != False, etc.

3. UI updates:

   • TechnicalPopover: display variable conditions with operator + value
   • LabelPropertiesPanel: same display as popover
   • Symbol mapping: == → =, != → ≠

Backward compatibility

Normalize legacy string[] format to new VariableCondition format with default truthy operator.

Priority

Medium - improves visibility but current functionality works.
