feat: implement custom fields, gantt view, calendar view, and file encryption
- Custom Fields (FEAT-001): - CustomField and TaskCustomValue models with formula support - CRUD API for custom field management - Formula engine for calculated fields - Frontend: CustomFieldEditor, CustomFieldInput, ProjectSettings page - Task list API now includes custom_values - KanbanBoard displays custom field values - Gantt View (FEAT-003): - TaskDependency model with FS/SS/FF/SF dependency types - Dependency CRUD API with cycle detection - start_date field added to tasks - GanttChart component with Frappe Gantt integration - Dependency type selector in UI - Calendar View (FEAT-004): - CalendarView component with FullCalendar integration - Date range filtering API for tasks - Drag-and-drop date updates - View mode switching in Tasks page - File Encryption (FEAT-010): - AES-256-GCM encryption service - EncryptionKey model with key rotation support - Admin API for key management - Encrypted upload/download for confidential projects - Migrations: 011 (custom fields), 012 (encryption keys), 013 (task dependencies) - Updated issues.md with completion status 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
