llm_dart_transport 0.11.0-alpha.1

Shared transport abstractions for llm_dart providers.

Changelog

0.11.0-alpha.1 - 2026-05-12

• Alpha release of the transport package.
• Provides shared HTTP, SSE, UTF-8 streaming, logging, and diagnostics helpers.
• Adds a shared multipart/form-data builder for provider packages that need upload request support.
• Remains provider/runtime neutral so concrete providers can share transport plumbing without depending on the AI helper, chat, Flutter, or root packages.
