Add two prototype factions, extend quest bundles with reputationGrants
and factionGateRules, freeze five-quest roster in validate_content.py,
and sync minimal server quest roster parity for green startup tests.
Register bundle JSON Schemas, parse bundle DTOs on QuestDefRow, and run
E7M2 prototype gates (presence, freeze table, cross-ref, mission_reward)
with skill catalog input from DI.
