* fix proxy key usage tracking and add OSS spend reporting
replace ProxyKey.disabled with finalizedAt to fix a race where keys
were disabled before their usage was synced, causing all HWM values to
be zero. retireKey now fetches final usage from OpenRouter and records
it atomically with optimistic concurrency. syncAccountUsage skips keys
that fail to fetch rather than recording false zeros.
other fixes:
- wrap OpenRouter API calls in retry logic (exponential backoff)
- reconcileStaleWorkflowRuns now retires proxy keys for completed runs
- subprocess activity timeout only tracks stdout (stderr retry loops
no longer prevent hung agent detection)
- add oss-spend script (single bulk fetch from OpenRouter) and
backfill-proxy-key-usage script
