feat(db): migrate fetched_at from TEXT ISO-8601 to INTEGER Unix epoch#348
Conversation
Adds a "Database Size:" row to the System Info section of the Info dialog, showing the on-disk size of usage.db formatted as B/KB/MB/GB. The value is read at dialog-open time; no privacy masking needed since file size is not sensitive. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
Switch provider_history and raw_snapshots fetched_at columns from 19-byte TEXT strings to 4-byte INTEGER epoch seconds, saving ~15 bytes per row. Adds V11 Evolve migration and legacy ConvertTimestampsToEpochIfNeeded path. All SQL comparisons updated; FetchedAt returned via strftime with 'Z' suffix so Dapper maps DateTimeKind.Utc correctly. Compaction tests truncated to hour/day boundaries to avoid flaky bucket-boundary failures. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
