US targets label three dimension values two ways: re-pin the Chronicle feed with one label each #1343

Problem

The pinned US Chronicle feed (Chronicle 51aa40f, consumer_facts_us_51aa40f.jsonl, facts_sha256 965a29ac…) labels three dimension values two ways, so the compiled US targets carry two labels for one value id:

Chronicle's own build-bundle reports each as a conflicting_value_label_across_packages warning. The value ids and constraints are right in every package; only the wording differs. Anything that groups targets by dimension value, such as the calibration dashboard's target tree, shows one value under two names.

Decision

One wording per value:

• under_1: "No adjusted gross income";
• all: "All returns, total";
• 85_plus: "Age 85 plus".

Fix

A label-only re-pin of the feed, as microcosm#940 did for the state AGI bands:

• A Chronicle feed branch from 51aa40f with only the package label changes: the week-47 change from Give each dimension value one Chronicle-declared label, keep the package's own wording beside it (consumer_fact.v5) chronicle#377 (6d74e42), soi-historic-table-2 and soi-table-1-1 for all, and census-pep-2024-national-age-sex for 85_plus. Each package's checks of the publisher's text stay as they are.
• Re-pin us/chronicle_feed.json and the files that restate the pin to the feed built there.
• Show that only labels, and hash fields that cover labels, change in the feed and in the targets compiled at 2024.

Chronicle main gets the week-47 change through chronicle#377. The full re-pin onto Chronicle main (#1030) is a separate change.
