docs: Distinguish command syntax differences between Gemini and Codex tools

- Add critical warnings in codex-unified.md that no wrapper script exists
- Clarify in intelligent-tools.md that Gemini has wrapper, Codex uses direct commands
- Prevent confusion about non-existent ~/.claude/scripts/codex
- Emphasize correct usage: gemini-wrapper vs codex --full-auto exec
- Clean up CLAUDE.md tool references for consistency

 -   **Purpose**: An AI-powered CLI tool for automated codebase analysis, intelligent code generation, and autonomous development workflows.
+-   **⚠️ CRITICAL**: **NO wrapper script exists** - always use direct `codex` command, never `~/.claude/scripts/codex`
 -   **Key Characteristic**: **No `--all-files` flag** - requires explicit `@` pattern references for file inclusion.
 -   **Directory Analysis Rule**: When user intends to analyze specific directory (cd XXX), use: `bash(codex --cd XXX --full-auto exec "prompt")` or `bash(cd XXX && codex --full-auto exec "@{**/*} prompt")`
 -   **Default Mode**: `--full-auto exec` autonomous development mode (RECOMMENDED for all tasks).

 -   **Basic Structure** (Priority Order):
     ```bash
     bash(codex --full-auto exec "autonomous development task")  # DEFAULT & RECOMMENDED
-    bash(codex --full-auto exec "prompt with @{patterns}")              # For specific control needs

 -   **Key Commands** (In Order of Preference):
     -   `bash(codex --full-auto exec "...")` ⭐ **PRIMARY MODE** - Full autonomous development
     -   `bash(codex --full-auto exec "...")` - Controlled execution when you need specific patterns
