feat: add Codex and Claude Code components

[dkozlov]

Summary

Adds local coding-agent components for OpenAI Codex CLI and Claude Code:

• Adds openai.runCodexAgent to run Codex CLI non-interactively from the SuperPlane app container.
• Adds claude.runClaudeCode to run Claude Code non-interactively from the SuperPlane app container.
• Adds a shared agentcli runner for CLI execution, timeout handling, stdout/stderr capture, and exit-code reporting.
• Installs @openai/codex and @anthropic-ai/claude-code in the dev app image.
• Registers Workflow v2 mappers/state handling for both components.
• Updates generated component docs for OpenAI and Claude.
• Adds unit tests for config validation, command construction, success routing, and failure routing.

Demo

A local demo canvas was created and run for Codex:

• Canvas: Codex CLI Repo Reviewer
• URL: http://10.8.0.2:8000/067def26-347b-4285-83fa-5e8af95f89e8/canvases/75c55881-0d9e-4d4e-aab2-ae721f92d8aa

The canvas triggers openai.runCodexAgent from a Start node and routes success/failure to Display nodes. The test run reached the Codex CLI component; execution failed with Quota exceeded, confirming the component path and failure routing while the local OpenAI API account lacks paid quota.
