Remove safeWebpackModuleExports and preferMetaModuleRuntime flags in favor of unconditionally applying both fixes: getExports always uses null-safe access (wexports[0]?.exports ?? null) IIFE checks Meta __debug runtime before __webpack_module_cache__ since Meta's module system is authoritative in Meta's environment Reverts to the simpler IIFE pattern per reviewer feedback.

Fix WebpackModuleRuntime.getExports() crash when module not found in __webpack_module_cache__ (e.g. browser MCP injecting empty cache). Null-safe access gated behind flag. Convert ModuleRuntime from eager IIFE to lazy getModuleRuntime() so GlobalFlags are respected. flag controls whether Meta's __debug runtime is checked before webpack's cache. Add REACT_ACTIVITY_TYPE (0xeae8) to IReactConsts, fix broken SymbolFor call, and register in visitor vtable to suppress "optimized visitors missing entry for Symbol(react.activity)" warnings. Upgrade react-testapp to React 19 canary with real component test and Vite __debug exclusion.

Address security vulnerabilities in the react-native-testapp Gemfile: activesupport: 6.1.7.10 → 7.2.3.1 (fixes 3 medium severity CVEs) rexml: 3.4.1 → 3.4.4 (fixes 1 low severity CVE, >= 3.4.2 required) This requires Ruby >= 3.2 (up from 2.6.10) since activesupport 7.2.x depends on connection_pool which needs Ruby 3.2+. Added .ruby-version for rbenv and updated the README with current setup instructions including rbenv-based Ruby installation and updated bundler commands. Tested simulator working as expected after
