The Alpine sqlite3 binary refuses to open /dev/stdout when running as
a non-root uid in a container ('Error: cannot open "/dev/stdout"'),
which breaks every backup attempt. Switch the dump path to stage the
snapshot in a temp file, then stream that file through gzip into the
pipeline. Adds streamSideEffect to the test mockRunner so the existing
gzip-wrap test can simulate the sqlite3 process writing to its
destination path.

- apps/agent/ — Go agent (WSS client, persistent queue, Docker
discovery, 5 DB drivers: PG/MySQL/Mongo/Redis/SQLite,
pre/post hooks, Prometheus metrics)
- apps/backupy-decrypt/ — standalone CLI for client-side decryption
- packages/proto/ — protobuf wire format (generated .pb.go committed
so the repo builds without protoc)
- docs/ — agent spec + wire-protocol contract
