Add a call to bootstrap_builtin_types() in init_command() (project.py)
immediately after initialize_project() returns. This seeds the built-in
resource types (fs-directory, git-checkout, etc.) into the database so
that "resource add" commands succeed without "Resource type not found"
errors.
The call is idempotent — invoking it multiple times will not create
duplicate types.
Also fix the TDD robot test (resource_type_bootstrap_git.robot) to
initialize a project before running "resource add", and fix a
pre-existing parallel test failure in plan_commands_new_coverage where
unittest.mock.patch could not reliably intercept PlanApplyService under
behave-parallel fork() workers.
