Signals: index the judge's query, six calls at once, one call per item on the server's key, tokens counted, a week's look-back an admin sets, edits that ask again only what was picked out (#274, #275, #276)

The judge's query read all of entries (605 MB, 566 ms) on every wake; an
index on each feed's items by date, as the query asks, and the rechecks
in a half of their own. Calls ran one at a time, about 150 ms each, so a
new Signal's month of about 8,000 items took twenty minutes: six in flight
now. On the server's key everyone's Signals on an item share one call.
TypeSafe's token counts go to /metrics and each jev span.

An item's text is cut at 1,000 characters instead of 2,000: on 55 real
items of eight podcast feeds and six Signals, on the development key,
1,000 changed none of 330 verdicts (nor did the same request twice) and
saved 12% of the input tokens, 1,266 to 1,112 a call; 500 changed one.

<h3>Tune out the noise</h3>
<p>Your feeds bring in more than anyone has time for. A Signal listens across all of them for one subject: give it a name, the words to listen for, and a sentence saying what you mean if the words are not enough. What fits lands in a list of its own, starting with the last month, and it keeps listening. To use Signals you will need an API key from <a href="https://typesafe.ai">typesafe.ai</a>, unless your server's admin provides one.</p>
