False deprecation warning: [features].codex_hooks when using [features].hooks

Description

Codex CLI v0.129.0 shows a deprecation warning on every session start:

[features].codex_hooks is deprecated. Use [features].hooks instead.
Enable it with --enable hooks or [features].hooks in config.toml.

However, config.toml already uses the correct key:

[features]
hooks = true

There is no codex_hooks key anywhere in:

• ~/.codex/config.toml
• Project-level .codex/config.toml
• Environment variables
• Codex Desktop app Preferences

The warning appears to be a false positive. The binary has an internal feature flag named codex_hooks (found via strings in the native binary at @openai/codex-darwin-arm64), and the deprecation check may be triggering on the internal flag name rather than the actual config key.

Steps to Reproduce

1. Set [features] hooks = true in ~/.codex/config.toml
2. Start a Codex CLI session
3. Warning appears

Expected Behavior

No deprecation warning when using the correct [features].hooks key.

Environment

• Codex CLI: v0.129.0
• Platform: macOS (darwin-arm64)
• Installed via: npm install -g @openai/codex
