fix: auto-refresh expired OAuth token for plan usage data (v3.0.1)

When the Claude Code OAuth token expires, /ocp usage showed 0% for all
plan limits. OCP now detects expiry and triggers a refresh via Claude CLI,
then re-reads the updated token from keychain. The 5-minute usage cache
prevents excessive refresh attempts.
