Pi/omp sessions kept falling into the Claude record when the api
field merely started with 'anthropic'. Kimi and other providers that
speak the anthropic-messages protocol (kimi-coding) were therefore
charged against Claude Code, showing k3 buckets under a Claude tab
even for a user without a Claude login.
Match the codex collector's provider-only attribution: only sessions
whose provider is exactly 'anthropic' count toward Claude usage.
Add a test proving a kimi-coding session sharing the
anthropic-messages api does not land in the Claude record.
