Add --export alias for LiNo output

[konard]

Summary

• Adds --export as an alias for the existing --out/--lino-output LiNo database export path in both C# and Rust CLIs.
• Keeps export formatting on the shared existing implementation, including numbered references and named references.
• Updates README documentation plus C# changeset and Rust changelog fragments.

Tests

• dotnet test --verbosity normal (168 passed)
• cargo test --all-features --verbose
• cargo fmt --all -- --check
• cargo clippy --all-targets --all-features

Fixes #24

[konard]

We already have --out options, so as export does output the same file, we should add it as alias, double check that we fully support numbered and named references, make sure everything covered with unit and integration tests for both Rust and C# version of the code. And also everything is well documented.

We need to ensure all changes are correct, consistent, validated, tested, logged and fully meet each and all discussed requirements in widest possible sense (check issue description and all comments in issue and in pull request, make sure each and every requirement listed before actually checking if they were addressed). Ensure all CI/CD checks pass.

Please plan and execute everything in a single pull request, you have unlimited time and context, as context autocompacts and you can continue indefinetely, until it is each and every requirement fully addressed, and everything is totally done.
