feat: Migrate Aliyun OSS Bucket to Terraform-like state engine

[Copilot]

• Add ALIYUN_OSS_BUCKET to ResourceTypeEnum in src/types/domains/state.ts
• Create ossOperations.ts in src/common/aliyunClient/ - OSS SDK operations wrapper
• Update src/common/aliyunClient/index.ts to use OSS operations
• Create ossTypes.ts - Type definitions for OSS bucket config and conversion functions
• Create ossResource.ts - CRUD lifecycle with state management
• Create ossPlanner.ts - Plan generation for bucket operations
• Create ossExecutor.ts - Plan execution for bucket operations
• Update src/stack/aliyunStack/index.ts to export new OSS modules
• Create unit tests for ossTypes and ossPlanner
• Run linting and build to verify changes
• Run code review and address feedback
• Run CodeQL security check (no issues found)

Code Review Feedback Addressed:

• Extracted ACL type to shared BucketACL enum in src/stack/bucketTypes.ts
• Created CommonBucketConfig, CommonBucketInfo, and CommonBucketInstance shared types
• Expanded OssBucketInfo to include comprehensive bucket information (owner, storage class, data redundancy, CORS, lifecycle, logging, etc.)
• Changed beforeEach to afterEach in ossPlanner.test.ts
• Removed duplicated property assignments in ossTypes.ts

Security Summary

No security vulnerabilities were discovered by CodeQL analysis.

<issue_description>## Summary
Migrate Aliyun OSS bucket resource management from ROS template-based deployment to the unified Terraform-like state management engine.

Background

Currently, Aliyun OSS buckets are managed via ROS CDK constructs in src/stack/rosStack/bucket.ts. This needs to be refactored to use the state-based workflow.

Current Implementation (to be migrated)

• File: src/stack/rosStack/bucket.ts
• Uses @alicloud/ros-cdk-oss, @alicloud/ros-cdk-ossdeployment, @alicloud/ros-cdk-dns, @alicloud/ros-cdk-ram
• Handles: ACL configuration, website hosting, static file deployment, custom domains, DNS records

Target Implementation

Create new modules under src/stack/aliyunStack/:

• Provider: ossProvider.ts - Aliyun OSS SDK operations
• Types: ossTypes.ts - Type definitions and config hash
• Resource: ossResource.ts - CRUD lifecycle with state management
• Planner: ossPlanner.ts - Plan generation
• Executor: ossExecutor.ts - Plan execution

Requirements

1. Create Aliyun OSS Provider (ossProvider.ts)

export const createOssBucket = async (context: Context, config: OssBucketConfig): Promise<void>
export const getOssBucket = async (context: Context, bucketName:  string): Promise<OssBucketInfo | null>
export const updateOssBucket = async (context:  Context, config: OssBucketConfig): Promise<void>
export const deleteOssBucket = async (context: Context, bucketName: string): Promise<void>
export const uploadStaticFiles = async (context: Context, bucketName: string, sourcePath: string): Promise<void>

Use ali-oss SDK instead of ROS CDK.

2. Create OSS Types (ossTypes.ts)

export type OssBucketConfig = {
  BucketName: string;
  ACL:  'private' | 'public-read' | 'public-read-write';
  Website?:  { IndexDocument: string; ErrorDocument:  string; ErrorCode: number };
  Domain?: string;
};
export const bucketToOssConfig = (bucket:  BucketDomain): OssBucketConfig => { ... };
export const computeBucketConfigHash = (config: OssBucketConfig): string => { ... };

3. Handle Features

• ACL management (private, public-read, public-read-write)
• Website hosting configuration
• Static file deployment from local path
• Custom domain binding with DNS records
• Server-side encryption

4. Update State Types

Add ALIYUN_OSS_BUCKET to ResourceTypeEnum in src/types/domains/state.ts

Acceptance Criteria

• OSS buckets can be created, updated, and deleted via state management
• Website hosting and static file deployment works
• Custom domain configuration works
• State file tracks bucket resources with config hash
• Drift detection works for bucket configuration changes

References

• Current ROS implementation: src/stack/rosStack/bucket.ts
• Tencent COS pattern: src/stack/scfStack/cosPlanner.ts

oss and cos should have same bucket defination, refactor to make oss and cos to reuse same logic.

[Copilot]

Refactored OssBucketConfig to use CommonBucketConfig from shared src/stack/bucketTypes.ts. OSS and COS now share the same base bucket configuration structure. Commit: 5166d83
