docs(examples): query the demo's log with a snapshot, not litelink - #107

The examples README opened the trades log with litelink.open. It now reads the same table through Stream.snapshot on the stream's metadata file. The main README said a snapshot given broker= reads the buffer too; it needs as_of_offset=LATEST as well, and now says so.

litelink.open(...)snippet that queries the trades demo's log is replaced withStream.snapshotonstreamcast-data/trades.metadata.json. It runs the samesqlandscan. A new note says that, while the broker is running,as_of_offset=streamcast.LATEST, broker="ws://127.0.0.1:8765/trades"adds the rows not yet published.broker=reads across both". A snapshot also needsas_of_offset=LATESTto read past the published end, so the sentence now says that.I ran both against a demo-shaped stream with 6 published rows and 4 unpublished. A plain snapshot returned 6 rows, and
LATESTwithbroker=returned 10. Thesqlandscanin the snippet returned the expected rows.🤖 Generated with Claude Code
