Two fixes for Codex config.toml compatibility:
1. ensureCodexHooksFeature: insert [features] before the first table header
instead of prepending it before all content. Prepending traps bare
top-level keys (model, model_reasoning_effort) under [features], where
Codex rejects them with "invalid type: string, expected a boolean".
2. generateCodexConfigBlock: use absolute config_file paths when targetDir
is provided. Codex ≥0.116 requires AbsolutePathBuf and cannot resolve
relative "agents/..." paths, failing with "AbsolutePathBuf deserialized
without a base path".
Fixes#1202
