[Copilot]

Release

Bumps WebUI to 0.0.19.

Previous release tag: v0.0.18

Changes since v0.0.18

Features:

• build-time, bundler-neutral state projection minimizes SSR hydration payloads across CLI, Node, Rust, WASM, FFI, .NET, webui-press, and examples (feat: add bundler-neutral state projection feat: add bundler-neutral state projection #390).
• Node Protocol.render() now returns a UTF-8 Buffer for lower V8/N-API overhead on large output (feat: return UTF-8 buffers from Node render feat: return UTF-8 buffers from Node render #402).

Fixes:

• docs home page scrollbar spans the full page width while content remains centered (fix: make docs home page scrollbar span full page width fix: make docs home page scrollbar span full page width #388).
• conditional hydration respects nested SSR ownership markers and no longer captures static siblings (fix: preserve conditional SSR hydration ranges fix: preserve conditional SSR hydration ranges #395).
• development proxy requests preserve encoded paths and queries for route-state resolution and API forwarding (fix: preserve encoded development proxy URLs fix: preserve encoded development proxy URLs #400).
• component connectedCallback() completes hydration synchronously when SSR DOM is available (fix: make component hydration synchronous fix: make component hydration synchronous #401).
• repeat reconciliation handles duplicate values safely and supports keyed identity and lifecycle cleanup (fix: make repeat reconciliation duplicate-safe fix: make repeat reconciliation duplicate-safe #403).

Docs:

• projection, development proxy, hydration lifecycle, and Node rendering guidance was updated alongside the corresponding behavior and API changes (feat: add bundler-neutral state projection feat: add bundler-neutral state projection #390, fix: preserve encoded development proxy URLs fix: preserve encoded development proxy URLs #400, fix: make component hydration synchronous fix: make component hydration synchronous #401, feat: return UTF-8 buffers from Node render feat: return UTF-8 buffers from Node render #402).

Maintenance:

• a Node addon runtime benchmark now covers protocol construction, buffered rendering, streaming callbacks, output equivalence, and named baselines (feat: add Node addon runtime benchmark feat: add Node addon runtime benchmark #398).
• release validation prebuilds shared JavaScript dependencies to avoid parallel TypeScript races and bypasses pnpm self-management stalls (fix: preserve encoded development proxy URLs fix: preserve encoded development proxy URLs #400).

Validation

• cargo xtask check
