Fix ANR caused by blocking SecureRandom initialization in AgentConfiguration

[Copilot]

UUID.randomUUID() was called during field initialization of AgentConfiguration, causing ANRs on app startup. The method uses SecureRandom internally, which can block for several seconds on some Android devices, particularly when invoked during static initialization.

Changes

• Deferred initialization: Changed sessionID field from eager (provideSessionId() call) to lazy (null) initialization
• Thread-safe lazy loading: Implemented double-checked locking in getSessionID() to initialize on first access
• Synchronized regeneration: Made provideSessionId() synchronized to prevent race conditions during explicit session ID renewal

Before

private String sessionID = provideSessionId();  // Blocks during class init

public String getSessionID() {
    return sessionID;
}

After

private String sessionID = null;  // No blocking during class init

public String getSessionID() {
    if (sessionID == null) {
        synchronized (this) {
            if (sessionID == null) {
                sessionID = UUID.randomUUID().toString();
            }
        }
    }
    return sessionID;
}

public synchronized String provideSessionId() {
    sessionID = UUID.randomUUID().toString();
    return sessionID;
}

The blocking UUID generation now occurs only when the session ID is actually needed, avoiding ANRs during app startup while maintaining thread safety and backward compatibility.

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)

This section details on the original issue you should resolve

<issue_title>com.newrelic.agent.android.AgentConfiguration.provideSessionId (AgentConfiguration.java:225)</issue_title>
<issue_description>NOTE: # ( ^^ ^^ )

Description

App faces ANR in some cases.

I have dug into the issue, it appears on this method:

public String provideSessionId() {
sessionID = UUID.randomUUID().toString(); --this line specifically
return sessionID;
}

Basically, this internally calls:
SecureRandom secureRandom = new SecureRandom();

This is cryptographically secure random number generation, which on some Android devices and OS versions can block for several seconds during initialization, especially if called very early during app startup (like in a ContentProvider static initializer). (As suggested by AI agent)

Steps to Reproduce

Occurs randomly during app startup, detected via firebase.

Expected Behavior

App should not throw ANR.
