zeekay 86788566d1 datastore: rebrand the Rust client and speak the Datastore wire protocol ...

Cut from the upstream v0.13.3 release tag (not HEAD) so this is a pure
rename with no behaviour change. v0.13.3 is what our consumers already
resolve to: insights/rust's Cargo.lock pins clickhouse 0.13.3 and its
manifest already declares `datastore` at 0.13.x.

The load-bearing change is the HTTP auth header rename. The Datastore
server reads only X-Datastore-User / X-Datastore-Key; the upstream names
return `401 Code: 194 Authentication failed`. Every un-renamed HTTP
client is therefore unable to authenticate at all — this is a
correctness fix, not branding.

- crate `clickhouse` -> `datastore`, `clickhouse-derive` -> `datastore-derive`;
  versions preserved exactly (0.13.3 / 0.2.0).
- derive macro emits `datastore::Row` in lockstep, so downstream
  `#[derive(Row)]` keeps resolving.
- User-Agent reports `datastore-rs/{version}`.
- test-harness env vars CLICKHOUSE_* -> DATASTORE_*; compose uses
  ghcr.io/hanzoai/datastore with /etc/datastore-server config paths.
- doc links point at docs.hanzo.ai/datastore.
- `publish = false`: the `datastore` name on crates.io belongs to an
  unrelated crate, so consume this by git tag, never by version range.

CHANGELOG is truncated to a fork notice rather than find-replaced —
rewriting upstream release history would manufacture changes Datastore
never shipped. References to upstream issues keep their numbers.
