MCP Health-Check — tavily key-sourcing simulator

Pick how the tavily MCP server gets its API key, then flip between the old (env-only) check and this PR's fix. Watch the false-positive session-start warning disappear.

SessionStart hook mcp-health-check.ts fix/mcp-health-op-read

1 · How does tavily get its key?

2 · Which hook logic?

Resolved .mcp.json entry

Session-start output

Faithful re-implementation of keyProvidedByConfig() + checkServer() from src/hooks/src/lifecycle/mcp-health-check.ts. The simulator runs the same regex and the same decision branches the hook does.
