Motivation

Upstream ty released 0.0.22 → 0.0.31 while our submodule was pinned to ~0.0.21. This PR catches up by bumping the ruff/ submodule to the latest openrewrite/ruff ty-types-2 tip (1f844143e8), fixing the API shim against breaking changes on ty's side, and exposing two new pieces of structured signature information that ty now makes available: Concatenate prefixes and ParamSpec tails.

Examples

Callable[Concatenate[int, P], R] — the leading int is now tagged, and the synthesized *args / **kwargs carry the ParamSpec name so consumers can collapse them back into P:

{
  "kind": "callable",
  "parameters": [
    { "name": "", "kind": "positionalOnly", "typeId": 7, "hasDefault": false, "concatenatePrefix": true },
    { "name": "args",   "kind": "variadic",        "typeId": 8, "hasDefault": false, "paramSpecName": "P" },
    { "name": "kwargs", "kind": "keywordVariadic", "typeId": 9, "hasDefault": false, "paramSpecName": "P" }
  ],
  "returnType": 10
}

Callable[P, R] — same paramSpecName treatment, no concatenatePrefix:

{
  "kind": "callable",
  "parameters": [
    { "name": "args",   "kind": "variadic",        "typeId": 4, "hasDefault": false, "paramSpecName": "P" },
    { "name": "kwargs", "kind": "keywordVariadic", "typeId": 5, "hasDefault": false, "paramSpecName": "P" }
  ],
  "returnType": 6
}

Plain signatures are unaffected — both fields are omitted when false / absent.

Summary

• Bump ruff/ submodule from f74e9836 to 1f844143 (openrewrite/ruff ty-types-2).
• API shim: ProjectDatabase::new(metadata, system) → ProjectDatabase::fallible(metadata, system) (upstream split the constructor and added a MisconfigurationStrategy parameter).
• API shim: collapse the per-variant match in supertypes_from_class_literal to ClassLiteral::explicit_bases, which now uniformly handles the new DynamicTypedDict / DynamicEnum variants.
• API shim: fold the new Type::Divergent(DivergentType) cycle marker into the Other fallback.
• Add concatenatePrefix: bool and paramSpecName: Option<String> to ParameterInfo, populated from sig.parameters().kind() in both registry.rs (for function / callable / boundMethod descriptors) and collector.rs (for CallSignatureInfo on ExprCall nodes).
• Add a TODO in registry.rs for TypedDict.extraItems — [ty] Infer the extra_items keyword argument to class-based TypedDicts as an annotation expression astral-sh/ruff#24362 landed the inference side, but the public accessor on TypedDictType is still unavailable.
• Document the new fields in README.md.

Test plan

• cargo check — clean.
• cargo test — 25/25 integration tests pass, including three new tests:
  • test_param_spec_signature (Callable[P, R])
  • test_concatenate_signature (Callable[Concatenate[int, P], R])
  • test_non_paramspec_signature_has_no_flags (regular def add(a: int, b: int) -> int)
• cargo build --release — clean.
• Smoke-tested --serve with initialize / shutdown.

All new fields are additive and skip_serializing_if-gated, so existing consumers are unaffected.
