refactor(delegation)!: consolidate commands with intelligent profile selection

BREAKING CHANGE: Replace 4 hardcoded commands with 2 intelligent commands:
- Old: /ccs:glm, /ccs:kimi, /ccs:glm:continue, /ccs:kimi:continue
- New: /ccs (auto-selects), /ccs:continue (auto-dects)
- Override with flags: /ccs --glm "task", /ccs --kimi "task"

This change:
- Adds intelligent profile selection based on task analysis
- Supports custom profiles without creating new commands
- Enhances session management with automatic profile detection
- Updates all help text, examples, and documentation
- Fixes CCS Doctor health checks for new command structure
