add phi memory compaction pipeline
ingest flow now fetches observations + interactions from phi's TurboPuffer
namespaces alongside github/tangled data. new dbt models stage and profile
per-user data. new compact flow (triggers on transform, parallel with brief)
synthesizes relationship summaries via haiku and writes them back to
TurboPuffer where phi reads them at conversation time.
