Reported entrypoint now comes from a helper before CLAUDE_CODE_ENTRYPOINT

What

Claude Code tells Anthropic's servers how it was started, called the entrypoint (for example, from the command line). Two places that send this label now ask a new helper first.

• The cc_entrypoint value in the billing header uses the helper's answer, then CLAUDE_CODE_ENTRYPOINT, then unknown.
• The entrypoint part of the claude-cli/ User-Agent (the identifying string sent with each request) uses the helper's answer, then CLAUDE_CODE_ENTRYPOINT, then cli.

Before this release, both read CLAUDE_CODE_ENTRYPOINT directly.

Why

If you set CLAUDE_CODE_ENTRYPOINT, it may no longer be the value reported, because the helper's answer now comes first. The label Anthropic receives for how Claude Code was started may change.
