Refactors Foundry around organization/repository ownership and adds an organization-scoped GitHub state actor plus a user-scoped GitHub auth actor, removing the old project PR/branch sync actors and repo PR cache.
Updates sandbox provisioning to rely on sandbox-agent for in-sandbox work, hardens Daytona startup and image-build behavior, and surfaces runtime and task-startup errors more clearly in the UI.
Extends workbench and GitHub state handling to track merged PR state, adds runtime-issue tracking, refreshes client/test/config wiring, and documents the main live Foundry test flow plus actor coordination rules.
Also updates the remaining Sandbox Agent install-version references in docs/examples to the current pinned minor channel.
