1.2.1

Changed

• Swapped contentEl.createEl('div', ...) for the more idiomatic
  contentEl.createDiv(...) in DuplicateModal, following the
  obsidianmd/prefer-create-el guideline. Purely stylistic — behavior
  unchanged.

Removed

• The temporary "Screenshots coming soon" placeholder from README.md
  (and its accompanying <!--...--> template block). Real screenshots
  will land later without a preview note in the meantime — placeholder
  text was tripping the community-plugin reviewer.

Notes

The reviewer also recommended migrating the .setWarning() button call
to .setDestructive(). That API requires Obsidian ≥ 1.13.0, but our
minAppVersion is still 1.4.4 for backward compatibility. Deferred
until we bump minAppVersion in a future release.
