[joshrotenberg]

Summary

Wrap codex exec review for code review with git integration.

• CodexWrapper.Review struct with builder functions
• Git diff modes: uncommitted changes, base branch comparison, specific commit

Review options

• prompt (optional additional context)
• uncommitted (review uncommitted changes)
• base (compare against base branch)
• commit (review a specific commit)
• title (PR/review title)
• model, full_auto, dangerously_bypass_approvals_and_sandbox
• ephemeral, json, output_last_message
• config, enable, disable (lists)

Convenience API

# Review uncommitted changes
CodexWrapper.review(uncommitted: true, working_dir: "/path/to/repo")

# Review against a base branch
CodexWrapper.Review.new()
|> CodexWrapper.Review.base("main")
|> CodexWrapper.Review.model("o3")
|> CodexWrapper.Review.execute(config)

Acceptance criteria

• Review struct with builder functions
• Review.execute/2 runs codex exec review, returns Result
• CodexWrapper.review/1 convenience function
• Tests for argument building

Depends on

• feat: Exec command and Result struct #2 (Exec command + Result)
