Summary

• Move tree-sitter-language-pack from >=0.8.0,<0.9.0 to >=1.23.1,<2.0.0 (pyproject.toml, requirements.txt).
• Fix the Dart analyzer for the 1.x Dart grammar, which parses Foo<T>(x) as a call.
• Fetch the pack grammars at Docker build time, because 1.x downloads them on first use.

Why

The Lean grammar exists only in the 1.x pack. I tested get_parser("lean") on 0.8.0, 0.9.1, 0.13.0 and 1.23.1, and only 1.23.1 loads it. A Lean 4 analyzer will follow in a stacked PR. The bump is separate so you can review it on its own: the cap below 0.9 came in with 8d4a6f5.

What breaks with 1.x, and the fix

With only the pin changed, two Dart tests fail:

• test_dart_analyzer.py::test_call_resolution_rules: Garage.open -> Item is missing.
• test_dart_flutter.py::test_riverpod_and_router_edges: carProvider -> Car is missing.

Both have one cause. In 0.8, Box<Item>(1) was a relational_expression, and _handle_generic_invocation recovered it from the node text. In 1.x, it is an identifier followed by a selector whose argument_part holds type_arguments. _process_chain already emitted the Box instantiation edge from that shape, but not the type-argument edges. It now does. The relational-expression path stays.

No test changed: the existing assertions are the regression tests for this.

Runtime grammar download

1.x downloads each grammar on first use and caches it under tree_sitter_language_pack.cache_dir(). The grammars CodeWiki takes from the pack are dart, go, javascript, typescript, vue and zig. So:

• The first run of those analyzers needs network access. When the download fails, the error is raised inside each analyzer's existing try/except. The file is logged and skipped, and the run continues.
• docker/Dockerfile downloads the grammars at build time, so the image runs offline.
• guides/development.md says to add a new pack grammar to that list.

Test plan

• pytest -q -o addopts="": 654 passed with 1.23.1 (2 Dart failures before the fix).
• ruff check codewiki tests and ruff format --check codewiki tests.
• docker build -f docker/Dockerfile . (not run locally).

Closing: the motivation was the Lean grammar, which is only in the 1.x pack, and we are holding the Lean analyzer. Thank you.
