feat: upgrade tree-sitter to 0.22.4 and tree-sitter-swift to 0.7.1

Upgrades:
- tree-sitter: ^0.21.0 → ^0.22.4
- tree-sitter-swift: ^0.6.0 → ^0.7.1

Benefits:
- tree-sitter-swift@0.7.1 ships prebuilds (no manual node-gyp needed)
- Fixes parsing of Swift 5.9+ features: #Predicate, typed throws, ~Copyable
- All 13 language parsers verified compatible with tree-sitter@0.22.4

Tested:
- All 141 query/import/call tests pass
- All 13 parsers (C, C++, C#, Go, Java, JS, Kotlin, PHP, Python, Ruby,
  Rust, TypeScript, Swift) parse correctly with 0.22.4
- PricePal (61-file iOS 26 project) indexes fully: 3,094 nodes, 10,459 edges
