Writing your session back to Strava

If you turn on write-back (Profile → Connections), Runsei adds the planned session's name and your Runsei stats — including the Execution Score — to your own Strava activity, with a "Powered by Runsei" line. It only ever writes Runsei's own content and never overwrites anything you've written yourself, and only on fresh runs. It's strictly opt-in and off by default.
