🌟 What is the purpose of this PR?

Remove the old eval::graph module (read path, filter expressions, convert, sink) and its compiletest suite (eval_graph_read_entity). Add the new mir_interpret compiletest suite. Delete the now-unused composite value types from hashql-core (Dict, List, Struct, Tuple, Opaque, Value, FieldAccessError), keeping only primitive re-exports.

PR Summary

Medium Risk
Large deletion on the query/eval path and public-ish hashql-core::value surface; callers must already use MIR/postgres eval instead of the removed graph compiler.

Overview
Removes the legacy graph read evaluation path from hashql-eval: the entire graph module (read compiler, filter/filter_expr compilation, path traversal into EntityQueryPath, value-to-parameter conversion, diagnostics) and the graph Cargo feature. hashql-eval and hash-graph-api / compiletest no longer depend on optional graph feature wiring for eval.

Strips composite runtime values from hashql-core: deletes Value, Dict, List, Struct, Tuple, Opaque, and related access errors; value now only re-exports primitives (Float, Integer, Primitive, String).

Test cleanup: drops the eval/graph/read/entity compiletest suite and all associated UI tests; removes EvalGraphReadEntitySuite registration. hashql-eval dev-deps are normalized (workspace futures-lite, sqruff-lib, type-system as dev-only).

Minor: #[inline] on Default for AST lowering helpers.

Pull request overview

Removes the legacy HashQL graph-read evaluation/compiler path (and its UI/compiletest suite) while simplifying hashql-core’s value surface area down to primitive re-exports. This aligns evaluation/testing around the newer MIR interpreter path and eliminates now-dead value/container types.

Changes:

  • Removed hashql-eval’s old graph module (graph read path/filter compiler/sink/convert/error) and the associated eval/graph/read/entity UI tests.
  • Removed composite value types from hashql-core’s value module, keeping only primitive re-exports.
  • Updated compiletest suite registration/dependencies and workspace dependency versions to reflect the removed graph feature path.
