docs: fix command name inconsistencies across documentation

Fix multiple command naming and parameter inconsistencies:

1. Command Name Fixes:
   - Change /cli:mode:bug-index to /cli:mode:bug-diagnosis
   - Affected files: COMMAND_REFERENCE.md, COMMAND_SPEC.md,
     EXAMPLES.md, GETTING_STARTED.md, GETTING_STARTED_CN.md,
     PROJECT_INTRODUCTION.md

2. Parameter Fixes:
   - Remove invalid --tool parameter from /workflow:lite-plan
   - The lite-plan command does not support --tool flag
   - Affected files: README.md, README_CN.md, COMMAND_SPEC.md

3. Invalid Command Fixes in PROJECT_INTRODUCTION.md:
   - Change /gemini:analyze to /cli:analyze --tool gemini
   - Change /qwen:mode:plan to /cli:mode:plan --tool qwen
   - Change /codex:mode:auto to /cli:execute --tool codex
   - Change /workflow:plan-deep to /workflow:plan
   - These legacy command formats are no longer valid

Impact:
- All documentation now matches actual command implementations
- Users will not encounter "command not found" errors
- Examples are now executable and correct
- Consistent command syntax across all docs
