Test Java agentless Feature Flags without the Java agent

[leoromanovsky]

Motivation

Java agentless Feature Flags must work without dd-java-agent.jar. Legacy Remote Configuration must remain agent-backed.

Changes and Decisions

• Add a Java launcher switch that omits -javaagent only for explicit no-agent cases.
• Add default CDN, explicit source precedence, last-known-good, and Remote Configuration rejection coverage.
• Keep existing Java agent-present coverage enabled.
• Add Moshi to custom provider artifact builds.
• Validate the behavior introduced by DataDog/dd-trace-java#12109.

Validation

• Local no-agent coverage: four cases passed.
• Local agent-present source and lifecycle coverage: 29 cases passed.
• The built Java process omitted -javaagent for no-agent cases and retained it otherwise.
