Greptile Summary

This PR fixes the anthropic-beta header sent during Claude Code quota-check requests by introducing a dedicated ClaudeCodeQuotaCheckHeader constant that omits context-1m-2025-08-07 (the 1M-token context beta), which is unnecessary for a minimal 1-token probe and was likely causing the quota check to fail.

• constants.go: New ClaudeCodeQuotaCheckHeader constant added — same as ClaudeCodeBetaHeader minus context-1m-2025-08-07. Extra alignment whitespace added to ClaudeCodeQuotaCheckModel line.
• claudecode_checker.go: CheckQuota now sends ClaudeCodeQuotaCheckHeader instead of ClaudeCodeBetaHeader for the anthropic-beta request header.

Confidence Score: 4/5

Safe to merge — the change is a targeted one-line swap to a narrower beta-header constant, and the new constant correctly drops the 1M-context beta flag that is irrelevant for a minimal quota-probe request.

Both changed files are small and focused. The new constant value is a strict subset of the existing ClaudeCodeBetaHeader, the omitted feature (context-1m-2025-08-07) has no bearing on a 1-token probe request, and the checker logic itself is unchanged. The only gap is a missing doc comment on the new constant.

No files require special attention; constants.go warrants a glance only for the missing comment on ClaudeCodeQuotaCheckHeader.
