Pull request overview

This PR aims to make PR drawer “head” (and related PR drawer metadata) behave consistently across repository/context transitions by ensuring programmatic form updates trigger workspace-metadata persistence, and by ensuring a fresh local workspace has a non-empty head branch that can be persisted/restored.

Changes:

• Added helpers to set PR drawer form values while emitting input events so workspace metadata persistence runs for programmatic updates.
• Ensured inactive/local workspaces start with a generated head branch and that startup flushes an initial workspace save early.
• Added Playwright coverage for bootstrapping persistence and head stability across repository changes.
