feat(mobile): show answer-choice subtitles in the agent question card

[iscekic]

Changelog for users

• Agent answer choices now show each choice description as muted supporting text beneath its label.
• Selected choices keep both the label and description readable on filled buttons.
• Choices without descriptions show only their labels, without an empty second line.
• Screen readers announce a described choice's label followed by its description.
• The approved repair changes no user-visible behavior.

Changelog for maintainers

• The subtitle joins the accessible name (<label>, <description>) instead of accessibilityHint, because TalkBack reads hint text and ignores the tooltip React Native fills from accessibilityHint.
• A choice without a description keeps its bare label as the accessible name and sets no hint.
• Label and subtitle use a full-width column inside the option button, preserving its existing height, padding, and selected background.
• The subtitle uses a smaller muted style and a translucent foreground color on the selected filled button.
• The feature reuses existing option and option-selected translations with the composed label; it adds no copy or catalog keys.
• Unit tests cover subtitle rendering, the no-description branch, and the accessible-name/no-hint contract.
• Review the option button first because accessible naming and selected contrast are risky; feature evidence collected on 2026-09-12 does not establish visual legibility.
• .kwf-keep-device: accepted — the unreferenced zero-byte artifact was removed. Replacement evidence from 2026-09-12 replaces repair-specific runtime proof: it shows no runtime change, so no live proof applies to the repair. Feature captures remain unaffected.

Owner request

Surface: the mobile app (apps/mobile).

The question tool should support a subtitle for the answer choices, same as the CLI.

Executive Summary

The question-card subtitle change is sound; the only finding is a stray empty .kwf-keep-device workflow artifact committed at the repo root.

SUGGESTION

File	Line	Issue
.kwf-keep-device	n/a	Zero-byte file added by this PR, absent from main, and referenced by no code/config in the repo. It looks like a local Kilo workflow/emulator keepalive artifact. Remove it unless the e2e tooling intentionally requires it in-tree.
