docs: sync the field counts and module map to 1.3.1

The telemetry field count is taken from inspect.signature, not from
memory, because that is the one the release checklist keeps catching.
llm-calls.md said 22 and was two rounds stale; fixing the title alone
would have left the table contradicting it, so tenant_id and meta are
documented too.

The production template needed no new column — it derives them with
LIKE. What it gained is an assertion that it must keep deriving them
and must not inline a column name, which is the drift that could
actually happen.

The changelog leads with the three breaking items. A patch number
carries no warning by design, so the entry has to.
