The live pipeline records only the final model step of an OpenCode turn,
so the usage dashboard showed roughly 42% of OpenCode's own totals. Add
an offline reconciliation ledger instead of touching the streaming path
(a previous attempt that fed cumulative counters into the live pipeline
made the chat/status UI numbers jump):
- shared: read and aggregate `~/.local/share/opencode/opencode.db` per
(day, model), exposed as `@hapi/protocol/opencodeUsage`
- hub: additive `usage_reconciliation` table (no schema bump, safe to
roll back), local scan at startup and every 30 minutes, and the usage
summary prefers snapshots over live events for reconciled sessions
- cli: each runner scans its machine's store every 30 minutes and reports
snapshots over the new `opencode-usage-report` socket event, covering
remote machines and sessions whose process already exited
- the hub-local scan skips sessions whose store lives on another machine,
so it can never wipe remotely reported rows
