perf(cache): skip rewriting unchanged CacheManager.set() records (#730)

Browse Source 
The disk cache's unchanged-payload skip now ignores a CacheManager.set() record's timestamp, so unchanged re-saves are skipped; a skip moves the file's mtime to the new timestamp instead, and readers take a record's age from the newer of the two (never more than an hour past the embedded timestamp). Per-plugin plugin_metrics:<id> records become one plugin_metrics_snapshot written at most once a minute, and CacheManager builds its ConfigManager on first use. On hdpi, cache file writes went from ~37 to 8.6 a minute.
