Proposed Changes

LENS-5983 DS-689

Some collections contain items that must stay in the list, while the others remain removable and new items can still be added. Collection could only allow or prevent removal for every item at once.

allowRemove and removeDisabledTooltip follow the existing allowAdd / addDisabledTooltip pair.

Potential Breaking Changes

None.

Acceptance Criteria

• The proposed changes are covered by unit tests
• The potential breaking changes are clearly identified
• A changeset is added for releasable changes, following CONTRIBUTING.md
• README.md is adjusted to reflect the proposed changes (if relevant)

🟡 Changes recommended

The public custom-layout interface omits the new removal callbacks, causing type errors, and the changeset lacks the package bump needed to publish the updated documentation.
