feat: add universal named types decorators

[konard]

Summary

• Merged the latest main branch into issue-23-e23fa86d, including the csharp/ and rust/ repository layout.
• Added C# INamedTypes<TLinkAddress> and NamedTypesDecorator<TLinkAddress> under the new C# project path; the decorator implements links operations through LinksDecoratorBase and named type operations through INamedTypes.
• Added Rust NamedTypes and NamedTypesDecorator parity for LinkStorage, using a separate names link database and external-reference names.
• Tightened name cleanup so removing or reassigning names does not leave stale name mappings, and duplicate name assignment moves the name to the latest link.
• Added C# changeset and Rust changelog fragments for release automation.

Reproduction / Requirement

Issue #23 requests a universal NamedTypesDecorator for ILinks that also implements INamedTypes. After main moved the repository to separate C# and Rust surfaces, the PR also needed equivalent Rust coverage. The new tests cover interface/trait availability, name set/get/reverse lookup/removal, delete cleanup, constructor path behavior, and duplicate-name reassignment.

Tests

• dotnet test --configuration Release --filter NamedTypesDecorator --verbosity normal (10 passed)
• dotnet test --configuration Release --verbosity normal (148 passed)
• cargo fmt --all -- --check
• RUSTFLAGS=-Dwarnings cargo clippy --all-targets --all-features
• node scripts/check-file-size.mjs --lang rust
• cargo test --test named_types_decorator_tests (6 passed)
• cargo test --all-features --verbose
• cargo test --doc --verbose

Fixes #23

Get latest changes from default branch.

Double check all everything is correct, and also mirror the same for Rust, add more test cases to ensure 100% tests coverage.

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, do as much as possible in one go, until it is each and every requirement fully addressed, and everything is totally done.
