fix(runner): add PREFECT_RUNNER_AUTO_PROVISION_UV opt-out for uv run auto-detection When a pyproject.toml declaring prefect as a dependency is present in the working directory, the workspace starter unconditionally switches to `uv run` to launch flow runs. This breaks pre-built Docker image deployments where dependencies are already installed at build time, causing `uv run` to re-create a virtual environment and re-download all deps on every flow run. Add `PREFECT_RUNNER_AUTO_PROVISION_UV` (bool, default True) setting that allows users to disable this behavior. When set to False, the runner skips the `uv run` command selection and falls back to the standard `python -m prefect.flow_engine` launcher. Co-authored-by: Chris Guidry <chris@prefect.io>

fix(deps): raise pydantic-settings lower bound to >=2.9.1 (#22075)

fix(deps): raise pydantic-settings lower bound to >=2.9.1 prefect imports pydantic_settings.exceptions.SettingsError which was added in pydantic-settings 2.9.0, but the declared lower bound allowed versions as old as 2.2.1. This caused ModuleNotFoundError at import time when an older pydantic-settings was installed. Raise the floor to >=2.9.1 (2.9.0 was already excluded) in both pyproject.toml and client/pyproject.toml. closes #22074 Co-authored-by: Alexander Streed <alex.s@prefect.io>

fix(orchestration): guard against ZeroDivisionError in RetryFailedTasks when retry_jitter_factor is set without retry_delay `RetryFailedTasks.after_transition` passes `base_delay` directly to `clamped_poisson_interval` when `retry_jitter_factor` is configured, but `clamped_poisson_interval(0, ...)` divides by zero in its exponential CDF computation, crashing the orchestration server. This happens whenever a task uses `@task(retries=N, retry_jitter_factor=X)` without specifying `retry_delay_seconds` (the default). In that case `run_settings.retry_delay` is `None`, which normalises to `base_delay = 0`, and the subsequent call to `clamped_poisson_interval` raises `ZeroDivisionError`. Fix: skip jitter and use `base_delay` directly when `base_delay == 0`. Jitter on a zero-second delay is meaningless anyway. A regression test `test_jitter_with_zero_delay_does_not_raise` is added to `TestRetryFailedTasks` to cover this path.
