Allow users to disable marking offline automatically

Editor assessment

Imperative and user-centric — 'Allow users to disable marking offline automatically' states who benefits and what changes — but the adverb placement breeds ambiguity: does it disable automatic marking, or mark offline automatically in a disabled state? 'Make auto-offline optional for users' or 'Add a setting to disable auto-offline' would be unambiguous. The body is empty beyond a properly formatted Co-authored-by trailer, so the where (profile settings?) and the default behavior are left for the PR to explain. Adopting the established 'auto-offline config' vocabulary in the subject would tie the log together. Structure is correct, feat is right, minor bump implied; the message is fine, just slightly imprecise at the word level.
