Summary

Part 2 of #671: Markdown versions compare formatted in read-only Milkdown, with a Formátovaně / Zdrojový kód switch to part 1's source compare. Stacked on #683.

Changes

  • Side by side keeps facing blocks level; one column shows removed text, blocks, rows and items where they stood.
  • Blocks align on equal blocks first, then by shared text; text changes come from presentableDiff. Tables compare by cell, rows known by their first cell.
  • A changed format is purple with a tooltip ("nově tučně"); a block names its changes of type and format on a chip after its text ("nadpis 2 → odstavec; nově tučně"). Legend below.
  • Předchozí / Další změna, summary "+3 −2 bloky", diacritics-insensitive search with a count. No collapsing, no zoom; no HTML runs, no image loads.
  • Versions equal formatted open the source compare.
  • markdown-diff.js is pure and tested in Node; SDD-012 states the compare.

Code Review

  • A search typed while a newly shown layout is still building is kept and runs once the layout is built.
  • Clearing the search in the text or code compare returns empty matches without folding both texts.
  • Comments on diffMarkdown and align shortened.
  • Verified in the browser: raw HTML in the compared versions shows as text, nothing executes, no image loads.

Code Review

  • The block label names each format stretch as its tooltip does and stays inside its column.
  • The hidden note after a format stretch is gone; the visible label names the change for assistive technology.

Compare Markdown versions formatted
0462e40 
A Markdown compare opens formatted in read-only Milkdown editors, side by
side with facing blocks level or in one column with the removed content in
place. Blocks align on the exact diff of equal blocks first, then by shared
text; text changes come from presentableDiff of @codemirror/merge, which the
CodeMirror bundle exports as diffTexts. Tables compare by cell, rows known by
their first cell. A change of marks or block type is named in a tooltip or a
chip. The Formátovaně / Zdrojový kód switch opens part 1's source compare,
which versions equal formatted show on their own.

Part of #671.

Keep a compare search typed while a layout builds
f0035c8 
A query typed while the Markdown compare of the layout just shown is
still building was dropped; it is now kept and searched once the layout
is built. Clearing the search of a text compare no longer folds both
texts. Shorter comments in the Markdown diff.

Name a block's format changes on a visible label
62e7e98 
A changed format was named only in a tooltip, which touch cannot reach.
Each block now names its changes of type and format on one label after
its text; the tooltip stays over the stretch. A long label wraps.

Name each format stretch once, as its tooltip does
6016333 
The label joins a block's stretch names as the tooltips show them and
stays inside its column. The hidden note after a stretch went, as the
visible label already reads the change out.

Stacked on #688.

## Summary
The editor toolbar gets Změny: the edited text against the version being
edited, or another picked version, in one column.

## Changes
- Text, code and Markdown source show the diff in the editor itself
(`unifiedMergeView`), so edits, undo, search, Ctrl+S and the
unsaved-changes guard work as before.
- Formatted Markdown shows the read-only formatted compare in place of
the editor; format buttons are disabled while it shows.
- Předchozí změna, Další změna and the summary move into
`CompareChanges`, shared with both preview compares.
- A version over 1 MB, not in UTF-8 or failing to load says why; the
edited text stays editable.
- SDD-012 states the editor's Změny.
