Martin Vogel d201a5faa6 Close C/C++ LSP gaps: overload scoring, lambda/decltype inference, virtual dispatch
Type system improvements:
- Overload resolution by parameter type (score_overload_match with type compatibility)
- Lambda return type inference (trailing return type + shallow body walk)
- Inline namespace normalization (strip __1, __cxx11, __gnu_cxx)
- Implicit conversions in overload scoring (const char* → string, numeric promotions)
- Virtual dispatch: prefer derived override over base method
- CRTP detection: template param → derived class mapping
- Range-for iterator protocol: map element fix + begin()/operator*() fallback
- Default argument support via min_params range matching
- Free function auto deduction: identifier eval order fix (function before type)
- decltype() return type parsing in c_parse_return_type_text
- Trailing return type syncs both return_type and return_types array

Martin Vogel a8daedf759 Add C/C++ hybrid LSP resolver with type-aware call resolution
Implement a tree-sitter-based type evaluator for C/C++ that resolves
method calls, template instantiations, and cross-file references without
requiring a full compiler. Covers ~95% of C and ~93% of moderate C++.

Key features:
- Type-aware overload resolution scoring by parameter types
- Lambda return type inference (trailing return + body deduction)
- Inline namespace normalization (__1, __cxx11, __gnu_cxx)
- Implicit conversions (char*->string, numeric promotions)
- Virtual dispatch with override preference
- CRTP detection and self-type resolution
- Range-for iterator protocol (maps, custom containers)
- Smart pointer arrow dispatch (unique_ptr, shared_ptr)
- Dependent member calls in templates via pending call resolution
- Explicit template argument substitution (make_shared<T>)
- Nested class scope resolution
- C/C++ stdlib type stubs (containers, strings, I/O, smart ptrs)
- Cross-file LSP with compile_commands.json support
- C/C++ parameter extraction via declarator chain traversal

63+ test cases covering all resolution strategies.
