feat: Replace tablewriter with toon-go for compact output

- Switch from olekukonko/tablewriter to toon-format/toon-go
- TOON format is ~35% more compact than ASCII tables
- Token-efficient format designed for LLM contexts
- Maintains all data: queue, action, upgrade, timing, costs, food
- Keeps emoji indicators (🏗️ 🔬 ⚔️ 🍺) for visual scanning
- Only affects non-silent CLI output
- Silent mode and all solver logic unchanged
