refactor: migrate prompt templates to standardized structure and enhance CLI command documentation

Template Migration:
- Move templates from .claude/prompt-templates/ to .claude/workflows/cli-templates/prompts/
- Rename and reorganize: bug-fix.md → development/bug-diagnosis.txt
- Rename and reorganize: code-analysis.md → analysis/code-execution-tracing.txt
- Rename and reorganize: plan.md → planning/architecture-planning.txt

CLI Command Enhancements:
- Add clear tool selection hierarchy (gemini primary, qwen fallback, codex alternative)
- Enhance analyze.md, chat.md with tool descriptions and agent context
- Enhance mode/code-analysis.md, mode/bug-diagnosis.md, mode/plan.md with Task() wrapper
- Add all necessary codex parameters (--skip-git-repo-check -s danger-full-access)
- Simplify descriptions while preserving core functionality

Agent Updates:
- Streamline cli-execution-agent.md (600→250 lines, -60%)
- Add complete templates reference for standalone usage
- Remove dependency on intelligent-tools-strategy.md

Reference Updates:
- Update test-task-generate.md template path references
- Delete duplicate bug-index.md
- All template paths now use ~/.claude/workflows/cli-templates/prompts/ format
