refactor(workflow): remove all .active marker file references and sync documentation

Core Changes (10 files):
- commands: cli/execute.md, memory/docs.md, workflow/review.md, workflow/brainstorm/*.md
- agents: cli-execution-agent.md
- workflows: task-core.md, workflow-architecture.md

Transformations:
- Removed all .active-* marker file operations (touch/rm/find)
- Updated session discovery to directory-based (.workflow/sessions/)
- Updated directory structure examples to show sessions/ subdirectory
- Replaced marker-based state with location-based state

Reference Documentation (57 files):
- Auto-synced via analyze_commands.py script
- Includes all core file changes
- Updated command indexes (all-commands.json, by-category.json, etc.)

Migration complete: 100% .active marker references removed
Session state now determined by directory location only
