Add username support to registration with validation, reserved words, and real-time availability checking (TASK-409). Backend: - ValidateUsername() with format/length/reserved word checks - 35+ reserved usernames (route conflicts, system terms) - GET /auth/check-username endpoint for real-time validation - handleBootstrap auto-generates username from name (D1) - handleRegister accepts optional username, auto-generates if omitted Frontend: - Register page: username field with auto-generation from name - Join/invite page: same username field in register mode - Debounced availability checking (400ms) via /auth/check-username - Inline status indicators (checking/available/taken) - API client: register() accepts username, new checkUsername() method
