v1.0.12

• Added golden render regression tests for the Markdown widgets, covering text formatting, emphasis, blockquotes, lists, tables, task lists, and code blocks. They render with real fonts and run in the local flutter test suite; like the existing image goldens they are platform-specific, and are skipped on CI (whose Flutter stable channel is unpinned) to avoid flaky pixel-exact diffs when the toolchain drifts
• Documentation: the 1.0.11 README overhaul documented the previously undocumented onTapLink and styleSheet APIs, resolving #123
