Subject: [PATCH 1/2] fix: remove unused date-fns dependency from
 sdk-communication-layer
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

date-fns is not imported anywhere in the package (or the monorepo) — it
is only declared in package.json and listed as a UMD global in the
rollup config. Consumers were pulling in the full date-fns v2 tree
(~25MB) for nothing, and the v2 pin also failed to dedupe against
date-fns v3/v4 in downstream apps.

Fixes #1352
