Bug Description

When using TUI v2 (chat.ui "tui"), the granular trust picker introduced in v1.27 does not appear when prompted to approve tool usage. Instead, the TUI shows only basic Yes/Trust/No options without the tiered scope selection (e.g., Full command → Partial command → Base command → Entire Tool for shell, or Specific paths → Complete directory → Entire Tool for read/write).

The chat.disableGranularTrust setting is confirmed set to false in ~/.kiro/settings/cli.json.

The granular trust picker works correctly in the classic/legacy UI (kiro-cli chat --legacy-ui).

Steps to Reproduce

1. kiro-cli settings chat.ui "tui"

2. kiro-cli settings chat.disableGranularTrust false

3. kiro-cli chat

4. Ask the agent to perform an action requiring tool approval (e.g., a shell command or file write outside cwd)

5. Observe that the approval prompt shows only Yes/Trust/No — no granular scope picker appears

6. Compare with: kiro-cli chat --legacy-ui

7. Same action now shows the full granular trust picker with tiered scope options

Expected Behavior

The TUI v2 approval UX should present the same granular trust picker as the legacy UI, allowing users to scope trust to exact commands, partial commands, base commands, specific paths, or directories — as documented in the v1.27 changelog and the TUI v2 docs which state: "For shell commands, you can trust at different granularity levels: exact commands, command prefixes, or base commands."

Additional Context

The TUI v2 documentation under "Approval UX" describes a "panel-based dropdown" with Yes/Trust/No and mentions granular shell command trust levels. However, in practice the tiered scope selection does not render. This may be a case where the disableGranularTrust setting is not wired into the TUI v2 code path, or the panel-based dropdown implementation doesn't include the picker component.

Thanks for opening this issue and for the detailed reproduction steps! It's really helpful to have the clear comparison showing that the granular trust picker works in the legacy UI but isn't surfacing in TUI v2 mode. A maintainer will take a look at this shortly — we appreciate you helping us make the TUI v2 experience match what's documented! 🙌
