Function run_repair_loop 

pub fn run_repair_loop(
    max_attempts: usize,
    attempt_failed: impl FnMut(usize) -> bool,
) -> (bool, usize)

Drive a bounded repair loop: call attempt_failed up to max_attempts times (1-indexed), stopping at the first attempt that reports success. Mirrors conditional.ts’s runRepairLoop: returns (recovered, attempts) and never loops past max_attempts — exhaustion is reported back (recovered = false) for the caller to loud-fail, not swallowed here.
