Update Import Path for WorkspaceInfoLocalRecord in Documentation and Codebase

[leoshi01]

When using from leptonai.api.workspace import WorkspaceInfoLocalRecord to import the WorkspaceInfoLocalRecord class, VSCode and other IDEs fail to recognize and auto-complete the class methods and properties. After investigation, I found that updating the import path to from leptonai.api.v0.workspace import WorkspaceInfoLocalRecord resolves the issue.

Steps to Reproduce
Use from leptonai.api.workspace import WorkspaceInfoLocalRecord in a file.
Try to auto-complete methods under WorkspaceInfoLocalRecord in VSCode.
Expected Behavior
The correct import path should be from leptonai.api.v0.workspace import WorkspaceInfoLocalRecord, allowing the IDE to resolve and auto-complete methods and attributes accurately.
