rename secrets.py to credential_store.py, enhance /status, add usage tracking

- Rename src/secrets.py → src/credential_store.py (avoid stdlib conflict) - Enhanced /status command: uptime, tokens, cost, context window usage - Session metadata now tracks input/output tokens, cost, duration - _safe_env() changed from allowlist to blocklist approach - Better Claude CLI error logging Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
