Every variable that changes runtime behavior now lives on one page,
docs/environment-variables.md: which client reads it, its default, and
its effect. It covers three variables that were undocumented
(MCP_LOG_FILE, MCP_INSPECTOR_LOG_DIR, LOG_LEVEL), the secret-store
variables previously only in the Docker guide, and the Node TLS
variables that answer #1936 (a self-signed https://localhost server).
The README docs table, the migration guide, docker.md and the four
client READMEs link to it.
