module: Complete Workbooks and Views SDK surface

[teesofttech]

Goal

Finish the Workbooks and Views module to prerelease quality.

Scope

• Stabilize list/get/delete workbook behavior.
• Fix publish behavior or split publish into its own tracked prerequisite.
• Add view listing and export coverage.
• Add workbook update support if included in this module milestone.
• Ensure pagination is supported where Tableau returns paged results.
• Use the shared authenticated client/session foundation.

Tests

• Unit tests for request URLs, auth headers, query parameters, response parsing, validation, and error paths.
• Integration tests for at least one workbook read path and one view read/export path where safe.
• Mutating tests such as publish/delete must be opt-in and clean up resources.

Docs / Examples

• Add examples for listing workbooks, fetching a workbook, listing views, exporting a view, and publishing if supported.

Release

When done, run build/test/pack and publish the next NuGet prerelease.
