Commit Message

test: pin `snapshot_to_unreachable_node_should_not_block` to fast backoff

The default `Config::backoff` of `"200ms"` parses as exponential doubling
up to a 1 s cap (`200, 400, 800, 1000, 1000, …`). This test sets a 2 s
wait for the leader to purge logs behind an unreachable node, and the
growing retry cadence does not give the snapshot transmitter enough
retry cycles on loaded CI to clear the inflight that blocks purge —
seen as `try_purge_log: log T1-N0.15 is in use by 2` followed by a
timeout.

Override the policy locally to `"10ms, 10ms"` — two equal anchors fit
as `k · aˣ` with `a = 1`, giving constant 10 ms retries. The test now
finishes in ~130 ms and has ample headroom under CI load.

The production default is intentionally left as-is: exponential to 1 s
is the right shape for real deployments. Tests that depend on specific
retry cadence should declare it.
