Added INIT-01 through INIT-04 requirements to REQUIREMENTS.md. Updated ROADMAP.md with Phase 11.1 goal, success criteria, and plan list. Created three plan files mirroring Phase 11 structure: 11.1-01 (DB migration, API routes, AgentInitialsPanel, FieldPlacer token), 11.1-02 (preparePdf agentInitialsData param + prepare route guard), 11.1-03 (human E2E verification checkpoint).
