Full Release Notes

## Changes

### Added

- Allow OpenRouter users to enter any model ID from provider settings with cached autocomplete suggestions for tool-capable models, while keeping the curated dropdown as the default when no custom model is set.

### Changed

- Use localized app tooltips instead of native browser titles across editor controls, panels, and menus.
- Update Claude Code MCP setup documentation and the docs landing screenshot.
- Ignore non-source Markdown files in the app dev watcher so documentation edits do not reload the running editor.

### Fixes

- Route Claude Code stdio MCP requests through the live OpenPencil app connection, including immediate disconnected errors when no document is connected.
- Keep MCP disconnected guidance focused on starting OpenPencil and opening a document.
- Improve agent-rendered JSX compatibility with Figma-style text, alignment, and rotation aliases; strip HTML comments; and report unsupported props from render tools.
- Load exact text font styles after MCP and AI tool mutations so newly created bold/weighted text renders immediately.
- Include text style fields in MCP `get_node` output so agents can verify generated text accurately.
- Keep provider settings tooltip/popover composition working in WebKit.
