[Unreleased]

query_sql_stream/3 (HTTP transport) now truly streams and no longer swallows errors (#10). Previously it used Finch.request/3, which buffered the entire response body and eagerly decoded every JSONL line before yielding — giving zero memory benefit over query_sql/3 — and it halted to an empty list on non-2xx statuses, transport errors, and unresolved databases, so every failure class looked like "zero rows". It now consumes the response with Finch.stream/5, decoding JSONL line-by-line with back-pressure (constant memory), and raises an InfluxElixir.StreamError on a missing database, a non-success HTTP status, or a transport error when the stream is enumerated.
InfluxElixir.Client.Local.query_sql_stream/3 now mirrors the HTTP client's error semantics (#11). Client.Local is the documented drop-in test double for Client.HTTP, but it still returned an empty stream on a query error or an unsupported operation while Client.HTTP raised — so consumer code that rescues InfluxElixir.StreamError (to avoid treating an outage as "no data") could not be exercised against the test double. It now raises InfluxElixir.StreamError on enumeration for both cases, matching Client.HTTP.

InfluxElixir.StreamError exception, raised while consuming a streaming query that cannot produce rows. Carries a :kind (:no_database | :http_status | :transport | :decode | :unsupported) plus :status/:body/:reason context. InfluxElixir.StreamError.stream/1 builds an Enumerable.t() that defers the raise to enumeration, shared by both client implementations.
Tests covering the HTTP :no_database/:transport paths (real Finch pool, no mocking), the Local :http_status/:unsupported paths, lazy (deferred) raising, and StreamError message construction.

Loosened decimal constraint to ~> 2.0 or ~> 3.0 (#9). Unblocks downstream apps from upgrading past decimal 2.4.1 (EEF-CVE-2026-32686) and from picking up ecto ~> 3.14 → ash ~> 3.29 chains. Surface used (Decimal.to_string/2, %Decimal{} pattern) is stable across 2 → 3.
Loosened grpc constraint to ~> 0.11 or ~> 1.0 (#9). Unblocks downstream apps from upgrading past grpc 0.11.5 (5 CVEs including EEF-CVE-2026-48853).
Defaulted the Flight client to the Mint gRPC adapter so the library doesn't pull in :gun, which became optional in grpc 1.0. Mint is already available via finch.
InfluxElixir.Supervisor now skips adding GRPC.Client.Supervisor as a child when grpc 1.0+ is present (1.0 auto-starts it via its own Application).

LocalClient now supports COUNT(*) as a scalar and DATE_BIN-bucketed aggregate.
LocalClient WHERE-clause parser now returns a 400 error for unrecognised clauses (e.g. LIKE) instead of silently matching all rows.

Regression tests for COUNT(*), explicit column-list SELECT, IN operator narrowing, write-timestamp preservation, and silent WHERE drop.
