v1.8.4

Patch Changes

• #229 774acbf Thanks @eXamadeus! - Allow the reported Claude Code version to be configured via the ANTHROPIC_CLAUDE_CODE_VERSION environment variable. Anthropic gates model access on this value server-side and moves that gate on its own schedule, so a newly-gated model previously required waiting for a plugin release. Setting ANTHROPIC_CLAUDE_CODE_VERSION to a major.minor.patch value now overrides the bundled default for both places the version is reported — the user-agent header and the billing header's cc_version — which are resolved from a single value so they cannot disagree. The variable is read once at startup; a malformed value is logged as an error and the bundled version is used instead, and a value older than the bundled version is honored but logged as a warning, since reporting an older version is what triggers the gate in the first place. Thanks to @johnnymo87 for pointing out that a lower override silently defeats the purpose of the setting.
