Resume session view omits reasoning/code edits; request optional raw transcript display

Bug

When resuming a Codex session, the view now loads only the user messages and the final assistant output. The intermediate reasoning and code edit steps are no longer shown.

This appears to have changed recently; previously the raw session view included the full transcript (reasoning + edits), which was helpful for understanding what changed and for auditing work.

Expected

Either:

• Restore the previous raw transcript view when resuming a session, or
• Keep the current behavior as default but provide a config.toml option to enable the full raw transcript view (including reasoning and code edits).

Why it matters

The raw transcript makes it much easier to understand what the agent actually did, especially for code edits across multiple files or sessions.

Thank you!
