fix: story branch push to bare repo; drain at 3 consecutive failures

createStoryBranch was pushing to 'origin' which doesn't exist — branches
never landed in the bare repo so agents couldn't clone them. Now uses
the project's RemoteURL (bare repo path) directly for fetch and push.

Raise drain threshold from 2 to 3 consecutive failures to reduce false
positives from transient errors.
