fix(csharp): qualified/alias constructor names, : base/: this initializers, generic type-arg strip (#2046)

* fix(csharp): bind qualified constructor names, capture : base/: this, fix generic strip

Mirrors the Java #1928 parsing-layer fixes for the C# scope-resolution path —
the same three defect classes exist verbatim in C#:

- Qualified / qualified-generic / alias-qualified constructor calls
  (`new Ns.Foo()`, `new A.B.Foo()`, `new Ns.Box<int>()`, `new MyAlias::Foo()`,
  `new global::Foo()`) bound only `@reference.call.constructor.qualified` with no
  `@reference.name`, so the central extractor fell back to the whole-expression
  anchor and the reference name became the raw `new Ns.Foo()` text (never
  resolved). Derive the simple-name tail via the existing `terminalTypeNameNode`
  helper (handles qualified_name, generic tail, and alias_qualified_name), and
  add a query arm for the top-level `alias_qualified_name` shape that was not
  captured at all.

- `: base(...)` / `: this(...)` explicit constructor initializers, modeled by
  tree-sitter as `constructor_initializer` and never matched by the scope query,
  dropped the chained-constructor CALLS edges. Synthesize them: `this` → enclosing
  type name; `base` → the base type's bare name (first base-list entry, which C#
  requires to be the base class). Arity attached for overload disambiguation.

- `interpretCsharpTypeBinding`'s qualifier strip used `lastIndexOf('.')` over the
  whole string, cutting inside a qualified generic type ARGUMENT
  (`Dictionary<string, Ns.User>` → `User>`). Make stripQualifier generic-aware:
  reduce only the segment before the first `<`, re-attaching the generic suffix —
  multi-arg generics stay intact so the `.Values`/`.Keys` collection-accessor
  unwrap keeps working.

Tests: capture-level unit tests for every constructor shape (incl. alias-qualified,
double-match guard) and `: base`/`: this` (incl. struct/record/mixed-base);
interpretCsharpTypeBinding unit tests (the corruption case + nullable/nested/
unknown-generic edges); end-to-end resolver tests with new fixtures. The
csharp-captures golden was regenerated — drift is purely additive (only the new
fixtures; zero existing-fixture digests changed).

* fix(csharp): enhance constructor resolution and namespace qualification

- Implemented qualified constructor name binding to resolve collisions between types in different namespaces.
- Added support for `: base(...)` and `: this(...)` constructor initializers to ensure correct edge emission in the scope resolution.
- Improved generic argument stripping to prevent incorrect parsing of qualified types.
- Introduced tests for new features, including handling of interface-only base classes and qualified constructor calls.

This update addresses issues related to constructor resolution and namespace qualification, ensuring accurate type references in C# code. Tests have been added to validate these changes.

* fix(csharp): implement namespace prefix tagging for file-level type definitions

- Updated the C# ingestion process to tag file-level type definitions with their enclosing namespace path using a new `namespacePrefix` field, without altering the `qualifiedName`.
- Enhanced the scope resolver to utilize the `namespacePrefix` for resolving same-tail collisions in constructor calls, improving accuracy in type resolution.
- Added unit tests to validate the new functionality, ensuring that namespace prefixes are correctly applied to both block-scoped and file-scoped types, while leaving namespace-free types untagged.

This change addresses issues related to namespace qualification and constructor resolution in C# code, facilitating better handling of type references.

* refactor(scope-resolution): share isOverloadableCallable via util

Extract the ctor/function/method overload predicate into
callable-labels.ts so graph-bridge registration and lookup stay aligned
without duplicated private copies in ids.ts and node-lookup.ts.
