feat(parser): allow keywords as method names

[akonwi]

Summary

• allow every Ard keyword in trait and implementation method-name positions
• preserve keyword semantics outside contextual member names, including call arguments
• distinguish fn mut() from mutating fn mut mut()
• preserve static generic-call recovery for keyword member names
• update Tree-sitter and Zed support for mutating keyword methods

Testing

• cd compiler && go test ./...
• gopls check on touched Go files
• cd tree-sitter-ard && npm test
• cd tree-sitter-ard && npm run test:binding
• Tree-sitter parse and highlight query checks

Dependency

• Depends on feat: support mutating keyword methods tree-sitter-ard#6 for the submodule update
