Major changes: - Migrate all handlers from Gin to Echo framework - Add new apperrors, echohelpers, and validator packages - Update middleware for Echo compatibility - Add ArchivedHandler to task categorization chain (archived tasks go to cancelled_tasks column) - Add 6 new integration tests: - RecurringTaskLifecycle: NextDueDate advancement for weekly/monthly tasks - MultiUserSharing: Complex sharing with user removal - TaskStateTransitions: All state transitions and kanban column changes - DateBoundaryEdgeCases: Threshold boundary testing - CascadeOperations: Residence deletion cascade effects - MultiUserOperations: Shared residence collaboration - Add single-purpose repository functions for kanban columns (GetOverdueTasks, GetDueSoonTasks, etc.) - Fix RemoveUser route param mismatch (userId -> user_id) - Fix determineExpectedColumn helper to correctly prioritize in_progress over overdue 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
