Implementation Tasks

1. Extend Init Guard

• 1.1 Detect existing OpenSpec structures at the start of openspec init and enter an extend mode instead of failing.
• 1.2 Log that core scaffolding will be skipped while still protecting against missing write permissions.

2. Update AI Tool Selection

• 2.1 Present AI tool choices even in extend mode, indicating which tools are already configured.
• 2.2 Ensure disabled "coming soon" tools remain non-selectable.

3. Generate Additional Tool Files

• 3.1 Create configuration files for newly selected tools while leaving untouched tools unaffected apart from marker-managed sections.
• 3.2 Summarize created, refreshed, and skipped tools before exiting with the appropriate code.

4. Verification

• 4.1 Add tests covering rerunning openspec init to add another tool and the scenario where the user declines to add anything.
