feat(knowledge): elevate throughput-definition to root level

Move throughput-definition.md from knowledge/principles/ to knowledge/ to reflect its status as the North Star principle. Update all references to use the new path.

 ## Development Workflow
 
-This system avoids traditional IDEs to enable **macro-level task management** instead of micro-level file editing. Using [tmux + git worktrees + Claude Code CLI](knowledge/procedures/tmux-git-worktrees-claude-code.md), you manage multiple AI agents simultaneously across parallel tasks - the foundation for 1000x AI engineer productivity. See [throughput definition](knowledge/principles/throughput-definition.md) and [OSE principle](knowledge/principles/ose.md).
