Add LiNo database export output

[konard]

Fixes #8.

Summary

• Resolved the branch conflicts against the current main layout.
• Added --out <path> as the preferred complete database export option, with --lino-output <path> kept as an alias.
• Implemented the export path in both the C# CLI and the Rust clink binary.
• Exported .lino files contain the entire database as sorted LiNo lines, using named references when available and numeric references otherwise.
• Quoted named references that contain spaces, LiNo separators, or quote characters so exported lines remain valid LiNo references.
• Updated README usage plus C# and Rust release notes.

Reproduction / Usage

clink '() ((child: father mother))' --out database.lino

Expected database.lino:

(father: father father)
(mother: mother mother)
(child: father mother)

The legacy alias is also accepted:

clink '() ((child: father mother))' --lino-output database.lino

Tests

• dotnet test csharp/Foundation.Data.Doublets.Cli.sln
• cargo fmt --all -- --check
• cargo clippy --all-targets --all-features
• cargo test --all-features --verbose
• Manual C# export smoke check with --out
• Manual Rust export smoke check with --out

We need to resolve conflicts, and add --out alias, that will be recommended in docs, but --lino-output can also stay.

So both options always output entire database to .lino file, if references are named - as named references (meaning we should directly write names in lino files as references), if no named references are enabled - just output plain numbered references.

We also must support all the same features in Rust version of the code, and cover everything heavily with tests.

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

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.
