Note

Low Risk
No application or library code changes in the diff—only version bumps, lockfile, changelog, and README install example.

Overview
Release 2.1.4 for the workspace (oxana, oxana-macros, oxana-web): versions, Cargo.lock, and the README cargo add pin move from 2.1.3 to 2.1.4.

The new CHANGELOG entry documents what ships in this release: RuntimeBuilder::only_queue / except_queue for allow/deny queue processing (including dynamic subqueues and cron scheduling behavior), RuntimeBuilder::failure_reporter with typed failures and execution metadata (including serialized job args) plus richer default Sentry reporting, and a fix to keep panic stacktraces when Sentry’s panic integration is used while events are deferred for reporter selection. The 2.1.3 note is trimmed so failure-reporting details live under 2.1.4 instead of being duplicated.
