Add DuckDB Cross Platform Support

[Dr Bill Mcilhargey (billmcilhargey)]

Add architecture-specific DuckDB library handling and improve error messages

Add DuckDB support for Linux x64 and Linux arm64 platforms

(moved to dev branch - rather than main branch from earlier PR)

aahmed-spec Aleksandar Nikolić (@alexandair) Tested on Ubuntu with ZeroTrustAssessment 2.3.0.

The package includes duckdb.dll and libduckdb.dylib, but no libduckdb.so. The error shown is about Visual C++ Redistributable.

Bill’s change looks like the right fix and enables me to generate the report on Ubuntu 24.04.

Could you review and merge this into dev? I can provide logs from my side if needed.

aahmed-spec Merill Fernando (@merill) , one concern with the current DuckDB setup: native libraries are vendored directly into src/powershell/lib, which makes the repo heavier and prevents Dependabot from tracking/updating them properly.

Could we move DuckDB to an external dependency model instead, e.g. NuGet + build/package-time asset copy?

If you’re open to this direction, I can take it forward.

Closing this original implementation because it has been superseded by a more complete RID-based approach in the active development work:

• DuckDB.NET.Data.Full and DuckDB.NET.Bindings.Full are pinned to 1.2.1 with a lock file.
• Managed and native assets are materialized at test/build time rather than committed or copied during module import.
• Native selection supports Windows x64/ARM64, Linux x64/ARM64, and macOS x64/ARM64.
• Windows ARM64 was validated natively with DuckDB v1.2.1.
• The complete PowerShell suite passes: 14,121/14,121.
• CI covers all six OS/architecture combinations.

Thank you for the testing and feedback on this PR; it directly informed the replacement design.
