codemap 0.0.7 — the one thing 0.0.6 added, now actually reachable

R1-C38-f1: `tool_restart_needed` compared a cached version with itself, so a warm
server never warned that it was running superseded code. The installed side is now
read fresh per call, and the regression test changes only the installation.

Schema 0.13, unchanged. Verified on the published wheel by driving the scenario the
feature exists for: serve, change the installation underneath, ask — reported on
both `stats` and `reload`. Published as codmap 0.0.7.
