feat: add TypeScript extension and LSP integration tests

Enhanced the anvomidav tooling with proper TypeScript configuration
and comprehensive integration tests.

**VSCode Extension:**
- Converted extension.js to TypeScript (extension.ts)
- Added tsconfig.json for proper compilation
- Compiled extension outputs to out/ directory
- All TypeScript features properly typed
- Extension compiles cleanly with zero errors

**LSP Integration Tests (8 passing):**
- Parser integration with valid anvomidav syntax
- Type checking integration
- Semantic validation (ISU rules)
- Multi-element program parsing
- Ice dance discipline support
- FileId handling across different IDs
- Empty program handling
- Parser error handling

**Test Coverage:**
- Tests use actual anvomidav syntax from examples
- Tests cover: jumps, spins, steps, combinations
- Tests validate parser, type checker, and semantics integration
- All tests pass successfully

**Build Artifacts:**
- anv-lsp binary: Successfully built (release mode)
- VSCode extension: Compiles to out/extension.js

**Feature Status:**
✅ LSP server (already complete - 512 LOC)
✅ VSCode extension (now TypeScript with types)
✅ Integration tests (8 comprehensive tests)
✅ Parser integration
✅ Type checking integration
✅ Semantic validation integration

The anvomidav LSP is fully functional and tested!
