0.30.4

• Remove the com.facebook.sdk.CodelessDebugLogEnabled meta-data from the plugin's Android manifest. It has been there since the first release and had no effect: in Facebook Android SDK 18.x the flag is read into FacebookSdk.getCodelessDebugLogEnabled() and nothing in the SDK reads that getter. Codeless event setup is gated server-side by Meta's fetched app settings (codelessEventsEnabled / getCodelessSetupEnabled()), not by this flag. Because library manifests merge into the host app, the entry also forced any app that wanted the key set to false to add tools:replace to win the merge — that workaround is no longer needed and can be removed.
• Docs: the README no longer advises enabling codeless debug logging for debugging (the flags are inert on both platforms; setDebugLoggingEnabled is the switch that does something), and CONTRIBUTING.md now records the pinned Graph API version as a release-time check with the three places the literal appears.
