## Changes

- Added `@active-note` and `@selection` composer completions for bringing the current Obsidian editor context into a Codex turn, including selected Markdown text as additional turn context.
- Added paste and drag-and-drop attachment support in the composer. Images are saved to the configured attachment folder as Obsidian embeds, while other files are inserted as wikilinks and sent to Codex as file mentions.
- Improved selection rewrite diffs and fixed settings dynamic-section display issues.
- Improved app-server diagnostics and cached metadata handling so transient probe failures and context changes do not wipe useful connection, tool, or thread information.
