Hellodebasishsahu 127475df84 feat(codex): add GPT 5.3, fix API translation, add thinking levels
- Add GPT 5.3 Codex model with thinking level variants (none/low/medium/high/xhigh)
- Extract thinking level from model name suffix (e.g., gpt-5.3-codex-high)
- Fix Codex translation: preserve openai-responses format for Droid CLI
- Add effort level logging in request logs
