Problem Statement
TimeWindow::hourly(timestamp) = (timestamp / 3600) * 3600.
While the existing fast_window does support power-of-two bitwise
optimization, the cache layer (hourly_cached) always stores one
entry per session — not per user, not per power-of-two window.
Expected Outcome
Per-user CachedWindow storage so cooldown_ms reads are O(1).
Acceptance Criteria
cleanup_rate_limits reduced to constant-time.- Test: 1000 user rate-limit reads in < 1 µs each.
Files Affected
