refactor: split classroomController.js into 7 domain files (phase 2 of 2)
1618-line monolith split into: classroom/_shared.js — GUEST_EVENTS, emitToSession, hasAccess, canDraw classroom/sessions.js — lifecycle + guest tokens (12 functions) classroom/strokes.js — CRUD + cursor + preview (7 functions) classroom/pages.js — page CRUD + theme (8 functions) classroom/chat.js — messages, reactions, attachments, export (7 functions) classroom/permissions.js — draw, hand, mute, screen, attendance (11 functions) classroom/sim.js — simulation relay (5 functions) classroom/admin.js — history, notes, templates, admin views (14 functions) classroomController.js is now a 9-line re-export facade. routes/classroom.js unchanged. All 65 exports verified. Tests pass. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
