feat: improve init wizard Enter key behavior

Update the tool selection wizard so pressing Enter on a highlighted tool
automatically selects it before proceeding to the review step. This aligns
with common CLI expectations where Enter confirms the highlighted item.

Changes:
- Add logic to select the currently highlighted tool when Enter is pressed
- Update help text to clarify that Enter selects the highlighted tool
- Maintain Space key for toggling multiple selections

This reduces friction during onboarding by matching user expectations,
especially for users who navigate to a tool and press Enter without
first toggling it with Space.

+## Why
+- Users frequently scroll to a tool and press Enter without toggling it, resulting in no configuration changes.
+- The current workflow deviates from common CLI expectations where Enter confirms the highlighted item.
+- Aligning behavior with user expectations reduces friction during onboarding.
+
+## What Changes
+- Update the init wizard so pressing Enter on a highlighted tool selects it before moving to the review step.
+- Adjust interactive instructions to clarify Enter selects the current tool and Space still toggles selections.
+- Refresh specs to capture the clarified behavior for the interactive menu.
+
+## Impact
+- Users who press Enter without toggling now configure the highlighted tool instead of exiting with no selections.
+- Spacebar multi-select support remains unchanged for power users.
+- Documentation better reflects how the wizard behaves.

+## MODIFIED Requirements
+### Requirement: Interactive Mode
+The command SHALL provide an interactive menu for AI tool selection with clear navigation instructions.
+#### Scenario: Displaying interactive menu
+- **WHEN** run in fresh or extend mode
+- **THEN** present a looping select menu that lets users toggle tools with Space and review selections with Enter
+- **AND** when Enter is pressed on a highlighted selectable tool that is not already selected, automatically add it to the selection before moving to review so the highlighted tool is configured
+- **AND** label already configured tools with "(already configured)" while keeping disabled options marked "coming soon"
+- **AND** change the prompt copy in extend mode to "Which AI tools would you like to add or refresh?"
+- **AND** display inline instructions clarifying that Space toggles tools and Enter selects the highlighted tool before reviewing selections

+## 1. Implementation
+- [x] Update the tool selection wizard to auto-select the highlighted tool when Enter is pressed without prior toggles.
+- [x] Refresh inline instructions copy so Enter behavior is clear.
+- [x] Adjust or add tests if needed to cover the new selection flow.
+
+## 2. Validation
+- [x] Run `pnpm run build`.
+- [x] Run `pnpm test` (or targeted suite) if applicable.
