v0.26.0-beta.1

Delta since previous beta (v0.26.0-beta.0) — 2 new changesets.

Patch Changes

• Fix copying from the editor dropping line breaks when you paste into other apps.

  Soft line breaks — the everyday single-newline wraps inside a paragraph,
  blockquote, or list item — used to be copied as a bare newline whose rendering
  relied on the editor's own styling. Gmail and other rich-text destinations strip
  that styling, so the lines merged into one on paste. They now copy as real line
  breaks that survive everywhere. Copying a partial selection that contained a
  <br> line break used to fail silently and paste as raw markdown source
  (pipes, dashes, and literal <br> text); those breaks now come through as
  proper line breaks too.

  Multi-line table cells also copy correctly to spreadsheets: a cell with an
  in-cell line break is exported as a quoted field so Excel and Google Sheets keep
  both lines in one cell instead of merging them or splitting the row.

  Checked items in a task list now keep their checked state when copied, so a
  ticked checkbox no longer pastes as unticked in apps that preserve checkboxes.

• Fix search snippets splitting an emoji across the truncation boundary, which left a lone UTF-16 surrogate in the JSON-RPC response and caused strict MCP clients (Rust / pydantic parsers) to reject it as invalid UTF-8. Snippets are now well-formed before serialization.
