Enum CacheKeepWarm 

pub enum CacheKeepWarm {
    Off,
    Auto,
    Hours(u32),
}

Prompt-cache keep-warm policy (cache_keepwarm, task #444). See docs/specs/cache-ttl-spec.md §7.

• Off (default): never ping.
• Auto: ping while the measured ping spend of the current idle period stays below the cost of the cache rewrite it prevents (ski-rental rule: at most 2× the optimal spend, at most ~one rewrite on an abandoned session), and for at most cache_keepwarm_auto_max_hours (default DEFAULT_CACHE_KEEPWARM_AUTO_MAX_HOURS) after the session went idle.
• Hours(n): the same bound, and additionally stop n hours after the session went idle — whichever comes first.
