Cline 4.1.0: one VSIX ships both the legacy and SDK-based extension behind a staged rollout

The stable VS Code extension becomes a combined A/B package: a single VSIX containing the current extension and the new SDK-based extension, with a loader that activates exactly one per window under a remotely controlled staged rollout starting at 1% of users. Settings and credentials are shared between the two, but tasks created on the new extension are not visible while running the old one.
