chore: revert removal of unused vars for versioning

- Add findPubliclyAccessibleResources function to PermissionService for bulk public resource queries
  - Add hasPublicPermission function to PermissionService for individual resource public permission checks
  - Update getAgentHandler to use hasPublicPermission for accurate individual agent public status
  - Replace instanceProjectId-based global checks with isPublic property from backend in client code
  - Add isPublic property to Agent type definition
  - Add NODE_TLS_REJECT_UNAUTHORIZED debug setting to VS Code launch config

+/**
+ * Generic base middleware factory that creates middleware to check resource access permissions.
+ * This middleware expects MongoDB ObjectIds as resource identifiers for ACL permission checks.
+ *
+ * @param {Object} options - Configuration options
+ * @param {string} options.resourceType - The type of resource (e.g., 'agent', 'file', 'project')
+ * @param {number} options.requiredPermission - The permission bit required (1=view, 2=edit, 4=delete, 8=share)
+ * @param {string} [options.resourceIdParam='resourceId'] - The name of the route parameter containing the resource ID
+ * @param {Function} [options.idResolver] - Optional function to resolve custom IDs to ObjectIds
+ * @returns {Function} Express middleware function
+ *
+ * @example
+ * // Direct usage with ObjectId (for resources that use MongoDB ObjectId in routes)
+ * router.get('/prompts/:promptId',
+ *   canAccessResource({ resourceType: 'prompt', requiredPermission: 1 }),
+ *   getPrompt
+ * );
+ *
+ * @example
+ * // Usage with custom ID resolver (for resources that use custom string IDs)
+ * router.get('/agents/:id',
+ *   canAccessResource({
+ *     resourceType: 'agent',
+ *     requiredPermission: 1,
+ *     resourceIdParam: 'id',
+ *     idResolver: (customId) => resolveAgentId(customId)
+ *   }),
+ *   getAgent
+ * );
