  "message": "[flutter_tools] Implement Diagnostics extension slice and doctor integration (#191162)\n\n## Description\n\nThis PR implements Step 3 of Flutter Tools Extensibility: the\nDiagnostics extension slice and doctor integration.\n\n### Architectural Overview\n1. **`package:flutter_tools_core`**:\n- Defines core, platform-agnostic diagnostic models: `ValidationType`,\n`ValidationMessage`, and `ValidationResult`.\n2. **`package:flutter_tools_extension`**:\n- Defines the `DiagnosticsExtension` interface and service contract\n(`getTitle()`, `runDiagnostics()`).\n3. **`package:flutter_tools_extension_linux_prototype`**:\n- Implements `LinuxExtensionDiagnostics` validator in the Linux\nprototype extension.\n4. **`packages/flutter_tools`**:\n- Implements `DiagnosticsExtensionClient` to query isolate extensions\nover RPC.\n- Introduces `ExtensionDoctorValidator` which adapts extension\ndiagnostic results into Flutter tool `DoctorValidator` instances.\n- Wires `ExtensionDoctorValidator` into `Doctor.validators` via\n`ExtensionManager`.\n- Deprecates duplicate diagnostic types in `doctor_validator.dart` in\nfavor of `package:flutter_tools_core` exports.\n\n## Related Issues\nPart of https://github.com/flutter/flutter/issues/190692\n\n## Tests\n- Added\n`packages/flutter_tools/packages/flutter_tools_core/test/diagnostics_test.dart`\n- Added\n`packages/flutter_tools/packages/flutter_tools_extension_linux_prototype/test/linux_diagnostics_test.dart`\n- Added\n`packages/flutter_tools/test/general.shard/extension_protocol/diagnostics_service_test.dart`\n- Added\n`packages/flutter_tools/test/commands.shard/hermetic/tool_extensions_integration_test.dart`\n- Added\n`packages/flutter_tools/test/integration.shard/tool_extensions_test.dart`\n- Updated existing doctor and validator tests in `commands.shard` and\n`general.shard`.",
