WA-OPS: Fix rubocop offenses on next (unblocks build gate)

[kitcommerce]

Problem

The next branch currently fails bundle exec rubocop with 4 autocorrectable offenses, causing the dispatcher build gate to fail across all PRs.

Goal

Make next rubocop-clean by fixing these existing offenses.

Offenses (current)

• Rakefile: spacing around <<
• core/lib/workarea/configuration.rb: indentation
• core/lib/workarea/ext/freedom_patches/bson_document.rb: trailing whitespace
• core/test/lib/workarea/elasticsearch/document_test.rb: trailing whitespace

Acceptance Criteria

• bundle exec rubocop exits 0 on next
• No behavioral changes; formatting-only

Notes

Once merged, rerun build gate on the ready-for-review queue.

[kitcommerce]

Dispatcher starting fix on a branch off next to unblock build gate across PRs.

[kitcommerce]

PR opened: #654 (targets next). This should unblock build gate failures across the review queue once merged.

[kitcommerce]

I ran on the current branch locally (Ruby 2.7.8, RuboCop 1.84.2) and it exits 0 with no offenses.\n\nIt looks like the previously-reported 4 autocorrectable offenses have already been resolved on , so there’s nothing left to change here.\n\nProposing we close this as done.

Closing as done: is already rubocop-clean.
