/**
 * Per-checkout install identifiers. Lets two NanoClaw installs coexist on
 * one host without clobbering each other's service registration or the
 * shared `nanoclaw-agent:latest` docker image tag.
 *
 * Slug is sha1(projectRoot)[:8] — deterministic per checkout path, stable
 * across re-runs, unique enough across installs.
 *
 * NANOCLAW_INSTALL_ID overrides the cwd derivation for deployments where
 * the checkout path is not a stable identity (copied or ephemeral trees), so
 * identity can come from the environment instead. The value flows into
 * docker labels, image names, and service unit names — hence the
 * conservative charset
