[Unreleased]

Nullability inference for schema-qualified tables, scalar subqueries in select lists, and expression-derived columns (see Writing Queries guide).
Structured errors for --infer connection failures and timeouts (CannotConnectToPostgres, PostgresConnectionTimeout) with actionable hints for PG* env vars, CLI flags, and metadata-file fallback.

Documented composite-type policy as reject-with-hints (aligned with Gleam Squirrel and flat Elixir row maps). Inference now attaches actionable hints for composites (kind: "c") and geometric point values.
Finalized unsupported-type policy for Postgres ranges/multiranges and remaining built-ins (interval, geometric, network, money, and related types): inference rejects them with actionable hints, and the Types guide documents workarounds.

First public release of Squirrelix (Hex package squirr_elix): typed Elixir query modules from plain .sql files via Postgres inference or metadata.
Mix tasks mix squirrelix.gen and mix squirrelix.check.
Guides for getting started, writing queries, types, and configuration.
GitHub Actions CI (format, compile, Credo, tests with Postgres 16) and Hex publish on v* tags.

Public Elixir modules and Mix tasks use the Squirrelix name (package/app remain squirr_elix). Repository: scripthungry/squirrelix.

Generated SQL and @doc strings are embedded with inspect/2 so #{} in .sql files cannot become Elixir interpolation in generated modules.
EXPLAIN nullability rejects multi-statement SQL before using the simple query protocol (required for $n + generic_plan).
Plan JSON decoding uses stdlib JSON (no undeclared Jason dependency).
Overwrite protection trusts the generation marker only in the file header.
