v0.1.18

Runtime syntax providers, Wasm grammars, and richer text and list controls.

New

• Syntax supports runtime language registration, language injections, and optional Wasm grammars with per-session query compilation.
• Text fields accept syntax spans and live typography updates; selectable Markdown gains reusable focus and copy handling.
• Variable-height virtual lists preserve scroll anchors, follow the tail, and report visible rows.

Changed

• Linked grammars move to bezel-syntax-std; consumers must install a provider or register their own languages.
• Tree-sitter moves to 0.27 and the minimum Rust version rises to 1.90.

Fixed

• Terminal tab markers no longer expand twice during text shaping.
• The gallery installs its syntax provider for native highlighting and generated browser samples.
• Variable-height list scrollbars honour Visibility::Scrolling: the thumb fades after the idle window unless it is being dragged.
