v0.44.1

Features

• Add min_attempts and absolute_max_elapsed_time_ms fields to BackoffStrategy. min_attempts is the minimum number of retry attempts that must fire before max_elapsed_time is honored; defaults to 0 (preserves existing behavior). absolute_max_elapsed_time_ms caps when a new retry can start (does not interrupt in-flight requests); defaults to None. Together these close a short-circuit where a single slow first attempt could exhaust the retry budget before any retry fired.
