Add rules edition setting for condition tooltips (5e/5.5e)

Introduce a settings modal (opened from the kebab menu) with a rules
edition selector for condition tooltip descriptions and a theme picker
replacing the inline cycle button. About half the conditions have
meaningful mechanical differences between editions.

- Add description5e field to ConditionDefinition with 5e (2014) text
- Add RulesEditionProvider context with localStorage persistence
- Create SettingsModal with Conditions and Theme sections
- Wire condition tooltips to edition-aware descriptions
- Fix 6 inaccurate 5.5e condition descriptions
- Update spec 003 with stories CC-3, CC-8 and FR-095–FR-102

Closes #12
