Initial commit: Personal Consolidation Dashboard (Phase 1 Complete)

Implemented a unified web dashboard aggregating tasks, notes, and meal planning:

Core Features:
- Trello integration (PRIMARY feature - boards, cards, lists)
- Todoist integration (tasks and projects)
- Obsidian integration (20 most recent notes)
- PlanToEat integration (optional - 7-day meal planning)
- Mobile-responsive web UI with auto-refresh (5 min)
- SQLite caching with 5-minute TTL
- AI agent endpoint with Bearer token authentication

Technical Implementation:
- Go 1.21+ backend with chi router
- Interface-based API client design for testability
- Parallel data fetching with goroutines
- Graceful degradation (partial data on API failures)
- .env file loading with godotenv
- Comprehensive test coverage (9/9 tests passing)

Bug Fixes:
- Fixed .env file not being loaded at startup
- Fixed nil pointer dereference with optional API clients (typed nil interface gotcha)

Documentation:
- START_HERE.md - Quick 5-minute setup guide
- QUICKSTART.md - Fast track setup
- SETUP_GUIDE.md - Detailed step-by-step instructions
- PROJECT_SUMMARY.md - Complete project overview
- CLAUDE.md - Guide for Claude Code instances
- AI_AGENT_ACCESS.md - AI agent design document
- AI_AGENT_SETUP.md - Claude.ai integration guide
- TRELLO_AUTH_UPDATE.md - New Power-Up auth process

Statistics:
- Binary: 17MB
- Code: 2,667 lines
- Tests: 5 unit + 4 acceptance tests (all passing)
- Dependencies: chi, sqlite3, godotenv
