[FEATURE] Add setting to configure default option in plan mode approval dialog

Problem Statement

When approving a plan after plan mode, I see this dialog:

❯ 1. Yes, clear context and auto-accept edits (shift+tab)

1. Yes, auto-accept edits
2. Yes, manually approve edits
3. Type here to tell Claude what to change

The default selection is option 1 which clears the context. I always want option 2 ("Yes, auto-accept edits") because:

1. Context preservation improves performance - For complex, multi-step problems, keeping the full conversation context helps Claude understand the broader picture and make better decisions during implementation
2. I already have auto-compact enabled - Context management is handled automatically, so forcing a clear at plan approval is unnecessary
3. Clearing loses valuable context

Every time I approve a plan, I have to press down arrow to select option 2 instead of accidentally clearing my context.

Proposed Solution

Add a setting (e.g., planApprovalDefaultOption) that allows users to configure which option is selected by default:

{
"planApprovalDefaultOption": 2
}

Or with named values:

• "clearAndAutoAccept" (current default)
• "autoAccept"
• "manualApprove"
