Rangarajan Ramaswamy 5dbbcf7dad feat: add VB.NET (.vb) language support via tree-sitter
This commit adds full VB.NET language support to graphify, raising the
supported language count from 25 to 26. The implementation follows the
established LanguageConfig pattern used by all other tree-sitter-backed
extractors.

New dependency:
- Adds optional extra [vbnet] backed by tree-sitter-vbnet (published
  to PyPI at https://pypi.org/project/tree-sitter-vbnet/0.1.0/).
  Install with: pip install graphifyy[vbnet]

graphify/detect.py:
- Added .vb to CODE_EXTENSIONS so VB.NET files are discovered during
  corpus ingestion and file-system watching.

graphify/extract.py:
- _import_vbnet(): import handler for imports_statement nodes; emits
  imports edges using the namespace_name child text.
- _vbnet_extra_walk(): extra-walk hook that intercepts namespace_block
  nodes, emits a namespace node, and recurses.
- _VBNET_CONFIG: full LanguageConfig covering class_block / module_block /
  structure_block / interface_block as class types; method_declaration /
  constructor_declaration / property_declaration as function types;
  invocation call nodes with target/member_access fields.
- VB.NET-specific branches in _extract_generic:
  * Class body: VB.NET has no wrapper body node; inherits and implements
    are named fields directly on the class_block. Emits separate inherits
    and implements edges for each base type, stripping generic arguments.
  * Constructor name: constructor_declaration carries no name field in
    the grammar; always resolves to New.
  * Function body: uses the declaration node itself as body sentinel so
    the call-graph pass can find invocations inside methods.
- extract_vbnet(path): public wrapper that delegates to _extract_generic.
- _DISPATCH['.vb']: routes .vb files to extract_vbnet.

pyproject.toml:
- Added vbnet = ['tree-sitter-vbnet'] optional dependency group.
- Added 'tree-sitter-vbnet' to the all extra.

tests/fixtures/sample.vb:
- New fixture file exercising: Imports statements, Namespace block,
  Interface, Class with Inherits + Implements, Module, Structure,
  Sub/Function/Property methods, and method calls.

tests/test_languages.py:
- Added 13 tests covering: no-error, class/interface/module/structure
  detection, method detection, imports relation, inherits edge,
  implements edge, and no-dangling-edges invariant.

README.md:
- Updated language count 25 to 26.
- Added VB.NET to language list and file-extension table.
