Hide selection mode in terminal suggest toolbar when quick suggestions disabled

[Copilot]

When quick suggestions are disabled (default), suggestions only appear when explicitly invoked, where the selection mode setting is less relevant and creates UI clutter.

Changes

Updated the when clause for three selection mode menu actions in terminal.suggest.contribution.ts:

• ChangeSelectionModeNever
• ChangeSelectionModePartial
• ChangeSelectionModeAlways

Each action now includes a condition to check if automatic suggestions are enabled:

when: ContextKeyExpr.and(
    ContextKeyExpr.equals(`config.${TerminalSuggestSettingId.SelectionMode}`, '<mode>'),
    ContextKeyExpr.or(
        ContextKeyExpr.equals(`config.${TerminalSuggestSettingId.QuickSuggestions}`, true),
        ContextKeyExpr.equals(`config.${TerminalSuggestSettingId.SuggestOnTriggerCharacters}`, true),
    )
)

Behavior

• Hidden: Both quickSuggestions and suggestOnTriggerCharacters are false (default)
• Visible: Either setting is true

Pull request overview

This PR hides the selection mode menu items in the terminal suggest toolbar when both quick suggestions settings are disabled (their default state). This reduces UI clutter when suggestions only appear when explicitly invoked, making the selection mode setting less relevant in the default configuration.

Key Changes
