Provide API to increment "operation counts" for a UID and tag, used to eventually derive bytes/operation stats. Internally is stored at network layer, but should belong at data layer. Switch profiling to use data layer stats, which are emulated by summarizing network layer details. Read packet counts from new /proc/ columns and collect them into NetworkStatsHistory. Prevent double-counting by ignoring values from first snapshot. Watch for duplicate /proc/ entries. Update tests to verify packet and operation counters.
