Summary

This PR fixes long-text rendering in the request_user_input TUI overlay while preserving a clear two-column option layout. (Issue #11093)

Before:

• very long option labels could push description text into a narrow right-edge strip
• option labels were effectively single-line when descriptions were present, causing truncation/poor readability
• label and description wrapping interacted in one combined wrapped line

After:

• option labels wrap inside the left column
• descriptions wrap independently inside the right column
• row measurement and row rendering use the same wrapping path, so layout stays stable

Problem

request_user_input needs to handle verbose prompts/options. With oversized labels:

• descriptions could collapse into a thin, hard-to-read column
• important label context was lost

Root Cause

In shared row rendering (selection_popup_common):

• rows were wrapped as a single combined line
• auto column sizing could still place desc_col too far right for long labels
• request_user_input rows did not provide wrap metadata to align continuation lines after the option prefix

What Changed

1) request_user_input rows opt into wrapped labels

File: codex-rs/tui/src/bottom_pane/request_user_input/mod.rs

• In option_rows(), compute the rendered option prefix (› 1. / 2.) and set wrap_indent from its display width.
• Apply the same behavior to the synthetic “None of the above” row.
• Add long-text snapshot test coverage (question_with_very_long_option_text + request_user_input_long_option_text_snapshot).

2) Shared renderer now has an opt-in two-column wrapping path

File: codex-rs/tui/src/bottom_pane/selection_popup_common.rs

• Add focused helpers:
  • should_wrap_name_in_column
  • wrap_two_column_row
  • wrap_standard_row
  • wrap_row_lines
  • apply_row_state_style
• For opted-in rows (plain option rows with wrap_indent + description), wrap label and description independently in their own columns.
• Keep the legacy standard wrapping path for non-opted rows.
• Use the same wrap_row_lines function in both rendering and height measurement to keep them in sync.

3) Keep column sizing simple and derived from existing fixed split constants

File: codex-rs/tui/src/bottom_pane/selection_popup_common.rs

• Keep fixed mode at 3/10 left column (30/70 split).
• In auto modes, cap label width using those same fixed constants (max 70% label, min 30% description), instead of extra special-case
  constants/branches.
• Add/keep narrow-width safety guard in wrap_two_column_row so extremely small widths do not panic.

4) Snapshot coverage

File: codex-rs/tui/src/bottom_pane/request_user_input/snapshots/ codex_tui__bottom_pane__request_user_input__tests__request_user_input_long_option_text.snap

• Add snapshot for long-label/long-description two-column rendering behavior.
