Add HugeGraph 1.7.0 API support with graphspace-aware paths: dynamic graph operations and context switching

[Copilot]

HugeGraph 1.7.0 introduces graphspace-aware API paths that require updating the Python client to support dynamic graph management operations. Based on the official HugeGraph 1.7.0 REST API documentation, this PR implements the correct graphspace-prefixed endpoints with JSON configuration format.

Changes

Dynamic Graph Operations (graphs.py)

Extended GraphsManager with runtime graph management using official graphspace-aware API endpoints:

# For HugeGraph 1.7.0+, all operations use graphspace-aware paths
client = PyHugeClient("127.0.0.1", "8080", user="admin", pwd="admin",
                      graph="hugegraph", graphspace="DEFAULT")

# Create graph with JSON configuration (POST /graphspaces/{graphspace}/graphs/{name})
config = {
    "gremlin.graph": "org.apache.hugegraph.HugeFactory",
    "backend": "rocksdb",
    "serializer": "binary",
    "store": "new_graph",
    "rocksdb.data_path": "./rks-data",
    "rocksdb.wal_path": "./rks-data"
}
client.graphs().create_graph("new_graph", config_dict=config)

# Clone graph (POST /graphspaces/{graphspace}/graphs/{new}?clone_graph_name={source})
config_override = {
    "backend": "rocksdb",
    "store": "clone",
    "rocksdb.data_path": "./rks-data-clone",
    "rocksdb.wal_path": "./rks-data-clone"
}
client.graphs().clone_graph("source", "target", config_dict=config_override)

# Delete graph (DELETE /graphspaces/{graphspace}/graphs/{name}?confirm_message=...)
client.graphs().delete_graph("temp")

# List all graphs (GET /graphspaces/{graphspace}/graphs)
graphs = client.graphs().get_all_graphs()

Context Switching (client.py)

Single client instance operates across multiple graphs and graphspaces:

client = PyHugeClient("127.0.0.1", "8080", graph="g1", graphspace="DEFAULT")
client.schema().getVertexLabels()  # Works on g1

client.switch_graph("g2")
client.schema().getVertexLabels()  # Now operates on g2, managers auto-recreated

client.switch_graphspace("space2")  # Switch graphspace context

Implementation

• API Compliance: All endpoints match official HugeGraph 1.7.0 REST API documentation with graphspace-aware paths
• Graphspace-Aware Paths: All operations use /graphspaces/{graphspace}/graphs/ prefix for 1.7.0+
• JSON Configuration Format: Graph creation and cloning use JSON (dict) format for 1.7.0+, not text/plain
• List Graphs: GET /graphspaces/{graphspace}/graphs
• Get Graph Info: GET /graphspaces/{graphspace}/graphs/{graph}
• Clear Graph: DELETE /graphspaces/{graphspace}/graphs/{graph}/clear?confirm_message=...
• Create Graph: POST /graphspaces/{graphspace}/graphs/{graph} with JSON body
• Clone Graph: POST /graphspaces/{graphspace}/graphs/{new}?clone_graph_name={source} with optional JSON body
• Delete Graph: DELETE /graphspaces/{graphspace}/graphs/{graph}?confirm_message=...
• Get Config: GET /graphspaces/{graphspace}/graphs/{graph}/conf
• Manager lifecycle: Added _clear_cached_managers() to invalidate cache on context switch
• Backward compatibility: Maintains existing functionality for HugeGraph 1.5.0 and earlier (uses legacy paths without graphspace prefix and text/plain format)

Note on Graphspaces

In HugeGraph 1.7.0+, graphspace is integrated into all graph API paths as /graphspaces/{graphspace}/graphs/. The graphspace parameter is required when initializing the client for proper URL routing. The implementation automatically detects the server version and uses appropriate paths and configuration formats.

Testing

• Comprehensive test suite for dynamic graph operations with JSON configuration
• Tests for graph/graphspace switching functionality
• Tests gracefully skip when admin permissions not available
• All tests updated to use dict-based configuration for 1.7.0+ compatibility

<issue_title>[Feature] hugegraph-python-client 支持最新的1.7.0版本的API</issue_title>
<issue_description>### Search before asking

• I had searched in the feature and found no similar feature requirement.

Feature Description (功能描述)

hugegraph升级到1.7.0版本后，API发生了较大的改动，导致hugegraph-python-client很多SDK已不再可用。
建议进行优化或重构：

1. 优化因hugegrapg1.7.0 版本升级，而失效或错误的SDK
2. 提供动态创建图 SDK
3. 提供创建图空间SDK
4. 可以通过一个PyHugeClient 就可以操作不同的图空间/图，不需要再实例化新的PyHugeClient

Are you willing to submit a PR?

• Yes I am willing to submit a PR!

<agent_instructions>先在留言区提供一个问题分析和功能实现的思路 (保持清晰易懂), 然后再进行代码编写, 描述里的 SDK 就是接口方法调用的意思, 尽可能让改动优雅/最小化满足需求</agent_instructions>

已根据 HugeGraph 1.7.0 官方 API 文档修正实现 (commit a1fb46e)：

主要修正：

1. ❌ 删除了 GraphspaceManager - 官方文档显示没有 graphspace 的 REST API（graphspace 是配置级特性）
2. ✅ 修正图创建 API：POST /graphs/{name} (body: text/plain 配置)
3. ✅ 修正图克隆 API：POST /graphs/{new}?clone_graph_name={source}
4. ✅ 修正图删除 API：DELETE /graphs/{name}?confirm_message=...

所有实现现在完全符合文档 /content/cn/docs/clients/restful-api/graphs.md 中的描述。

6.3 Mode

合法的图模式包括：NONE，RESTORING，MERGING，LOADING

• None 模式（默认），元数据和图数据的写入属于正常状态。特别的：
  • 元数据（schema）创建时不允许指定 ID
  • 图数据（vertex）在 id strategy 为 Automatic 时，不允许指定 ID
• LOADING：批量导入数据时自动启用，特别的：
  • 添加顶点/边时，不会检查必填属性是否传入

Restore 时存在两种不同的模式：Restoring 和 Merging

• Restoring 模式，恢复到一个新图中，特别的：
  • 元数据（schema）创建时允许指定 ID
  • 图数据（vertex）在 id strategy 为 Automatic 时，允许指定 ID
• Merging 模式，合并到一个已存在元数据和图数据的图中，特别的：
  • 元数据（schema）创建时不允许指定 ID
  • 图数据（vertex）在 id strategy 为 Automatic 时，允许指定 ID

正常情况下，图模式为 None，当需要 Restore 图时，需要根据需要临时修改图模式为 Restoring 模式或者 Merging
模式，并在完成 Restore 时，恢复图模式为 None。

主要修正：

1. ✅ 所有 API 路径现使用 /graphspaces/{graphspace}/graphs/ 前缀
2. ✅ 创建和克隆图使用 JSON 格式请求体（dict），而非 text/plain
3. ✅ 列出图：GET /graphspaces/{graphspace}/graphs
4. ✅ 查看图信息：GET /graphspaces/{graphspace}/graphs/{graph}
5. ✅ 清空图：DELETE /graphspaces/{graphspace}/graphs/{graph}/clear?confirm_message=...
6. ✅ 创建图：POST /graphspaces/{graphspace}/graphs/{graph} (JSON body)
7. ✅ 克隆图：POST /graphspaces/{graphspace}/graphs/{new}?clone_graph_name={source} (JSON body)
8. ✅ 删除图：DELETE /graphspaces/{graphspace}/graphs/{graph}?confirm_message=...
