test: update claude-provider tests for sandbox changes

Updated tests to reflect changes made to sandbox mode implementation:

1. Changed permissionMode expectation from 'acceptEdits' to 'default'
   - ClaudeProvider now uses 'default' permission mode

2. Renamed test "should enable sandbox by default" to "should pass sandbox configuration when provided"
   - Sandbox is no longer enabled by default in the provider
   - Provider now forwards sandbox config only when explicitly provided via ExecuteOptions

3. Updated error handling test expectations
   - Now expects two console.error calls with new format
   - First call: '[ClaudeProvider] ERROR: executeQuery() error during execution:'
   - Second call: '[ClaudeProvider] ERROR stack:' with stack trace

All 32 tests in claude-provider.test.ts now pass.
