Patch release with the :sliding_window ETS fixes from #210 (closes #209).

• Bump @version to 7.5.1
• Date the CHANGELOG section

7.5.1 - 2026-10-26

• Fix SlidingWindow ETS backend counting denied hits, which could deny staggered retrying callers forever. Behaviour change: a client that keeps hitting after being denied no longer extends its own block; ETS now matches Redis here. (fix(ets): don't count denied hits in sliding window #210)
• Fix SlidingWindow ETS backend recording at most one hit per microsecond per key, which let concurrent hits past the limit. (fix(ets): don't count denied hits in sliding window #210)
• Fix SlidingWindow ETS backend raising Enum.EmptyError on the deny path under contention; it now returns {:deny, 1}. (fix(ets): don't count denied hits in sliding window #210)

After merge: tag v7.5.1 on the merge commit to trigger the Hex publish workflow.
