Feature | Optional window title 31-char-length-limitation on Linux/GTK

Problem / Motivation

Backlog item has related primitives, but lacks explicit triage, dedicated API contract, and targeted regression coverage.

Current behavior

Relevant primitives exist in the files listed above, but this backlog item does not have a complete, explicit InfiniFrame contract with dedicated coverage.

Expected behavior

Define explicit API/behavior for this migration item, implement in managed + native layers where needed, and add focused tests/documentation.

Proposed solution

Implement this incrementally:

1. Define/adjust the managed public API in InfiniFrame.Shared.
2. Wire implementation in InfiniFrame and InfiniFrame.Native where required.
3. Add focused tests (tests/InfiniFrameTests*) and docs updates (docs/docs/guides/*, docs/docs/migration/*).

Alternatives considered

• Keep as unsupported and document migration limitation.
• Provide a workaround-only approach without first-class API.

Use case

Applications migrating from Photino expect this behavior and currently need custom handling for "Optional window title 31-char-length-limitation on Linux/GTK".

Technical proposal

Scope implementation to: core managed runtime (src/InfiniFrame/*, src/InfiniFrame.Shared/*, src/InfiniFrame.Js/*). Keep behavior deterministic across Windows/Linux/macOS and document platform-specific limitations explicitly.

Additional context

Photino reference: tryphotino/photino.NET#267
