`netclaw stats` skills_loaded resets on daemon restart — read from daily_stats instead

[Aaronontheweb]

Problem

DailyStatsActor._totalSkillsLoaded is a process-lifetime, non-persisted counter. The field comment at src/Netclaw.Daemon/Gateway/DailyStatsActor.cs:22 says it explicitly: "Process-lifetime totals (never reset, never persisted — lost on restart)". netclaw stats reads this value via DaemonStatsService.SkillsLoadedTotal → DailyStatsActor.QueryProcessStats → ProcessStatsResult.SkillsLoadedTotal.

Result: every daemon restart silently resets the displayed lifetime counter to 0, masking real activity from before the restart. The daily_stats SQLite table already has historical per-day totals that would survive a restart, but they're not surfaced through netclaw stats.

Evidence

daily_stats shows non-zero historical skills_loaded:

date_key	skills_loaded
2026-04-08	1
2026-04-09	1
2026-04-10	0
2026-04-11	0

But netclaw stats always shows 0 because the daemon restarted at 2026-04-10 22:14 UTC, wiping the in-memory lifetime counter.

Options

1. Sum from daily_stats on query. In DailyStatsActor, change QueryProcessStats to read persisted rows + any unflushed in-memory _pending accumulators. Most accurate; no new state.
2. Persist lifetime totals to a new table. Write a lifetime_totals row that gets updated on each flush. Simpler to query but adds schema.
3. Display both "today" and "lifetime" in netclaw stats. Keep the volatile counter for the process-lifetime number but add a persisted total read from daily_stats.

Option 1 is simplest and doesn't require schema changes.

Affected

• src/Netclaw.Daemon/Gateway/DailyStatsActor.cs — QueryProcessStats handler, _totalSkillsLoaded field
• src/Netclaw.Daemon/Gateway/DaemonStatsService.cs:32-33,57 — query call site
• src/Netclaw.Cli/Tui/StatsPage.cs:144 — display (no change needed if upstream value becomes correct)
• src/Netclaw.Cli/Program.cs:1227 — netclaw stats plain-CLI path (no change if upstream fixed)
