v0.17.0

Added

• submit: Add 'spice.submit.updateOnly' configuration option to default to --update-only for upstack, downstack, and stack submit operations.
• submit: Add 'spice.submit.template' configuration option to automatically select a template when multiple PR templates are available.
• repo sync: Add 'spice.repoSync.closedChanges' configuration option to control how git-spice handles closed change requests.
• branch checkout: Allow checking out remote branches by name. This will create a local branch and allow git-spice to start tracking it.

Changed

• branch checkout: With --detach, prompt now allows selecting any branch, including those checked out in other worktrees.

Fixed

• submit: If a pre-push hook fails, surface messages printed to stdout in the error.
• restack: Fix issue where restack operations would leave the target branch checked out instead of the previously checked out branch, even when no restack operations were performed.
