Lint: Map ClassMethod and Expr_MethodCall to tracking issues in UnsupportedRegistry

[PurHur]

Problem

phpc lint reports generic messages for OOP syntax in 003-MiniWebApp:

unsupported Expr_MethodCall
unsupported Unsupported class body element: PHPCfg\Op\Stmt\ClassMethod

lib/Lint/UnsupportedRegistry.php has no entries for these kinds, so contributors cannot see #58 / #145 in lint output or docs/unsupported-syntax.md.

Goal

Register mappings so lint output includes GitHub issue numbers:

CFG kind	Issue
Stmt_ClassMethod / class body method	#58 (implementation), #145 (visibility/ctors follow-up)
Expr_MethodCall	#58

Scope

• Add kinds to UnsupportedRegistry::KIND_TO_ISSUE (exact php-cfg class names from Linter diagnostics)
• Regenerate or update docs/unsupported-syntax.md via existing script/check
• Assert in test/unit/MiniWebAppSkeletonTest.php that lint JSON mentions #58 for method call line

Acceptance criteria

./phpc lint examples/003-MiniWebApp/public/index.php 2>&1 | grep -E '#58|#145'

Verification

./script/ci-local.sh --filter MiniWebAppSkeletonTest

Local/Docker only — no GitHub Actions.

Dependencies

• Does not implement OOP — Language: Class methods and property access in JIT #58 / Language: Visibility, constructors, and destructors #145 remain language work
• Pairs with ServeAotTest: PATH_INFO front-controller (closes #453) #456 (include graph) for cleaner --all reports
