Re-pinning Chronicle past chronicle#350 adds state charitable targets #1245

PolicyEngine/chronicle#350 adds eight IRS Historic Table 2 measures to every state row of soi-historic-table-2-state-broad-2022, for TY2022: 408 facts.

It also moves the congressional-district charitable_* concept to Table 2.1's irs_soi.contributions_deduction. measure_id is unchanged.

What happens on the next re-pin, as read at microcosm 7253402fb:

• Feed. tools/build_us_chronicle_feed.py selects record sets and periods, not measures. All 408 facts therefore enter the rebuilt feed. us/chronicle_feed.json rows and facts_sha256 move, and so does target_parity_feed_families.json: HT2 6,674 → 7,082 if nothing else changes.
• charitable_amount / charitable_returns. These map to charitable_deduction (itemizers only) in us_runtime/fiscal_targets.py:151,234. They become state targets with role soi_fiscal_distribution, which enters state, full and state_cd and survives national_state. In state_cd, tools/us_acs_local_cd_surface.py replaces the charitable sibling bridges (itemized_deductions_amount, return_count) with these HT2 state parents. District blocks are then rebased to them, subject to the 1.25× band.
• docs/us-acs-local-soi-target-surface.md. It lists charitable_* as HT2 gaps, so that section and the surface goldens need updating.
• The other six ids. mortgage_interest_paid_* (unmapped on purpose, fiscal_targets.py:176), taxes_paid_deduction_* and taxable_state_local_income_tax_refunds_* map to nothing. They bind no target.

This is a target-surface change. Review it in the re-pin PR rather than taking it in silently. Analysis: ~/PolicyEngine/_reviews/chronicle-ht2-state-schedule-a/microcosm-impact.md.
