refactor(security): simplify security logic

[github-actions]

Closes #555

Applied changes based on Issue #555.

I’ve refactored src/security/security.ts for improved readability, modularity, and minor performance gains while preserving all existing behavior. Key changes:

• Extracted and reused the repo type from ActionConfig via a local Repo type alias.
• Consolidated and cleaned up JSDoc (removed duplicated/misplaced comments, clarified parameter docs).
• Destructured the permission response inline, and replaced the small array .includes() check with a Set for clearer intent.
• Simplified maskSensitiveInfo by chaining .filter()/.sort() and using .reduce() to apply all secrets, removing an explicit loop and temporary variable.
• Tidied import ordering so that all imports come first, followed by the type alias.

These adjustments keep the same logic and external interface but make the code easier to follow and marginally more efficient.

Diff highlights:

-import type { ActionConfig } from '../config/config';
-import { toErrorMessage } from '../utils/error';

-// Reuse repository info type from action configuration
-type Repo = ActionConfig['repo'];
+import type { ActionConfig } from '../config/config';
+import { toErrorMessage } from '../utils/error';
+
+// Reuse repository info type from action configuration
+type Repo = ActionConfig['repo'];
