Summary:
`JSIndexedRAMBundle` was a deprecated legacy-architecture class (annotated `[[deprecated("This API will be removed along with the legacy architecture.")]]` and guarded by `#ifndef RCT_REMOVE_LEGACY_ARCH`) for parsing indexed RAM bundles. It was only ever instantiated by `Instance::loadRAMBundleFromString` and `Instance::loadRAMBundleFromFile`, and those two `Instance` methods have no callers anywhere in fbsource: the old Android entry point `CatalystInstanceImpl` that used to call them has been deleted, and the new architecture (`ReactInstance` / bridgeless) routes `loadScriptFromFile` through `loadJSBundleFromFile` in the new runtime, never touching the legacy `Instance`. The only remaining user was its own unit test.
This removes `JSIndexedRAMBundle` and the two dead `Instance` RAM-bundle loaders that referenced it:
- Delete `JSIndexedRAMBundle.cpp`, `JSIndexedRAMBundle.h`, and `JSIndexedRAMBundleTest.cpp`.
- Remove `loadRAMBundleFromString` / `loadRAMBundleFromFile` from `Instance.cpp` / `Instance.h` and drop the now-unused include.
- Drop `JSIndexedRAMBundle.h` from `CXXREACT_PUBLIC_HEADERS` in `cxxreact/BUCK`.
- Update the committed C++ API snapshots accordingly.
The broader legacy RAM-bundle machinery (`RAMBundleRegistry`, `JSModulesUnbundle`, `Instance::loadRAMBundle`, `JSIExecutor::setBundleRegistry`) is left in place; it belongs to the same `RCT_REMOVE_LEGACY_ARCH` legacy bridge and can be removed as a follow-up.

Summary:
`Instance::loadRAMBundle` was a deprecated legacy-architecture method (annotated `[[deprecated("This API will be removed along with the legacy architecture.")]]` and guarded by `#ifndef RCT_REMOVE_LEGACY_ARCH`) that loaded a RAM bundle through a `RAMBundleRegistry`. It has no callers anywhere: the two `Instance` methods that used to feed the RAM-bundle path (`loadRAMBundleFromString` / `loadRAMBundleFromFile`) were already removed together with the `JSIndexedRAMBundle` parser, and nothing else ever invoked `loadRAMBundle` directly.
This removes the dead method and its public C++ API snapshot entries:
- Delete `Instance::loadRAMBundle` from `Instance.h` and `Instance.cpp`.
- Drop the `loadRAMBundle` line from the six committed C++ API snapshots.
The private `Instance::loadBundle` / `loadBundleSync` helpers are kept (still used by `loadScriptFromString` and `setSourceURL`), and the rest of the legacy RAM-bundle machinery (`RAMBundleRegistry`, `Instance::registerBundle` and its `NativeToJsBridge` chain) is left in place; it belongs to the same legacy bridge and can be removed as a follow-up.
Changelog: [Internal]
Summary: `Instance::supportsProfiling()` was declared in `Instance.h` but had no definition anywhere and no callers. A declared-but-never-defined non-virtual member function cannot be invoked (any use would be a link error), so this is unreachable dead code left over from an earlier refactor. This removes: - The `supportsProfiling()` declaration from `Instance.h`. - The corresponding entry from the six committed C++ API snapshots. Changelog: [Internal]
Summary: `Instance::initializeRuntime()` (the no-argument legacy `Instance` method) was declared in `Instance.h` but had no definition and no callers. `Instance::initializeBridge` calls `nativeToJsBridge_->initializeRuntime()` — a different method on `NativeToJsBridge` — and the only `instance->initializeRuntime(...)` call site in the tree is the new-architecture `ReactInstance::initializeRuntime(options, callback)`, an unrelated class with a different signature. A declared-but-never-defined non-virtual member function cannot be invoked (any use would be a link error), so this is unreachable dead code. This removes: - The `initializeRuntime()` declaration from `Instance.h`. - The corresponding entry from the six committed C++ API snapshots. Changelog: [Internal]
Summary: `telemetryTimePointToSecondsSinceEpoch()` in `ReactCommon/react/utils/Telemetry.h` was a `static inline` helper that converted a `TelemetryTimePoint` to seconds since the UNIX epoch, but it had no callers anywhere. This is a pure dead-code removal. The sibling `clockCast` helper it used is left in place (it remains part of the public API surface). Changelog: [Internal] Differential Revision: D108012910

Summary: `ClearableSynchronizedPool` (an `internal` Kotlin class in `ReactAndroid/.../common/`) was a variant of androidx `Pools.SynchronizedPool` adding a `clear()` method, but it was never instantiated or referenced anywhere. The live event pools (`OnLayoutEvent`, `PointerEvent`, `TouchEvent`, `ScrollEvent`) use androidx `SynchronizedPool` directly. This removes the orphaned class.
