Pull request overview

Adds a metadata-only “set target ref” initialization path to support single-branch mode: projects can be initialized (target ref + related metadata) without switching the user onto gitbutler/workspace, and the UI messaging/flows are updated accordingly.

Changes:

• Introduces set_target_ref_and_init_project in but-workspace and exposes it through but-api (server/Tauri/SDK) for setting target metadata without changing the checked-out branch.
• Updates Desktop + Lite clients to call the new command when singleBranch is enabled, including UI copy/loading states that no longer imply a branch switch.
• Adds Rust tests + Playwright coverage for the single-branch onboarding path and supporting e2e git assertions.
