queryd (D5) needs the same HTTP client to catalogd that ingestd uses,
but the client lived in internal/ingestd — having queryd import from
ingestd would invert the data-flow direction (ingestd is upstream of
queryd; the package dep should not point back). Extract to a shared
internal/catalogclient/ package now, before D5 forces it under
implementation pressure.
Adds the List(ctx) method queryd will need for view registration.
Unit tests cover Register success/conflict and List success/error
paths against an httptest.Server fake.
ingestd's import flips from internal/ingestd → internal/catalogclient;
the wire format and behavior are unchanged. All four smokes (D1/D2/D3/
D4) PASS unchanged. DuckDB cgo path re-verified with the official
github.com/duckdb/duckdb-go/v2 (per ADR-001) on Go 1.25 + arrow-go.
