The CLAUDE_INTERNAL_FC_OVERRIDES env var no longer overrides feature flags.

The CLAUDE_INTERNAL_FC_OVERRIDES environment variable no longer has any effect. getEnvironmentOverrides() previously read and JSON-parsed this variable to override GrowthBook features, but it now unconditionally returns null, so any feature overrides set through this variable are silently ignored.
