~anthropic/claude-sonnet-latest → A (6:4)

Commit A fixes a real production bug (Reddit blocking OAuth-required requests) with a targeted, well-tested retry/refresh mechanism and clear error surfacing. Commit B is a large URL-encoding refactor mixed with an unrelated YouTube-normalization feature; it changes room URLs to a less readable format (short+slug concatenated without separator) and touches many call sites/tests for cosmetic reasons, increasing churn risk without a clear necessity or bug motivation.
