- Simplify `hermes-engine.podspec`: always read `HERMES_VERSION_NAME`, use V1 source files, remove legacy inspector subspecs
- Simplify `hermes-utils.rb`: remove `hermes_v1_enabled()` function, always use `250829098.0.0-stable` branch, always use `.hermesversion` tag file
## Changelog:
[iOS][Removed] - Remove the RCT_HERMES_V1_ENABLED from Cocoapods

#56731) Summary: - Remove all dead C++ code behind `!defined(HERMES_V1_ENABLED)` guards in `HermesExecutorFactory.cpp` and `HermesInstance.cpp` - Delete `Registration.h`, `Registration.cpp`, `ConnectionDemux.h`, `ConnectionDemux.cpp`, and `ConnectionDemuxTests.cpp` (entirely legacy code) - Remove `HERMES_V1_ENABLED` compile definition from `react-native-flags.cmake` - Remove `HERMES_V1_ENABLED` cache variable from Android `CMakeLists.txt` This is Phase 1 of removing legacy Hermes support. Since Hermes V1 is already the default on all platforms and the 0.86 branch has been cut, all legacy Hermes code is dead and can be safely removed. ## Changelog: [General][Breaking] - Remove Legacy Hermes from C++ code ## Test plan - [x] Android: `./gradlew :packages:rn-tester:android:app:assembleDebug` — BUILD SUCCEEDED - [x] iOS: `xcodebuild` rn-tester on iPhone 16 Pro simulator — BUILD SUCCEEDED Reviewed By: cortinico Differential Revision: D104228879
