Replace dead Northeast and California local reference URLs

[MaxGhenis]

Summary

Part of the repo-wide audit of dead reference URLs outside tax.ny.gov (follow-up to #9711 and #9730). This PR covers Vermont, Connecticut, New York Labor, Maine and California county and city sources (Vermont Tax and DCF, CT General Assembly and OEC, NY DOL, Maine Legislature, San Francisco, Santa Clara, Contra Costa, Alameda and San Diego counties, University of Hawaii).

• 22 dead URLs, cited by 63 references, now point to a live copy of the same document, a live official page with the same content, or a pinned Wayback capture of the dead URL with the same #page.
• Only references change. A script checked that every changed line under parameters/, variables/ and docs/ differs from the old line only inside URLs. The one exception is the max_au_size.yaml reference title, changed after review to name CDSS ACL 23-74.
• policyengine_us/tests/code_health/known_dead_reference_urls/northeast_ca.toml lists 22 of the dead prefixes, so the offline guard from Replace dead NY tax department reference URLs #9711 fails if they return.

How each URL was checked

1. Dead: GET with curl -sL -A "Mozilla/5.0" on 2026-09-30, rechecked with a Chrome user agent. A 403, 429 or bot challenge counted as unknown, not dead, and was rechecked inside a real browser page; URLs still behind a bot wall were left unchanged. A 200 that landed on a home, search, login or not-found page counted as dead.
2. Replacement: one research agent per batch looked for the same document on the agency's current site, then for an official page stating the same content for the same period, then for a pinned Wayback capture. Each mapping records the quoted content it checked.
3. Independent verification: a second agent re-checked every live replacement and a sample of the Wayback ones against the values the citing file uses (pdftotext on the cited #page for PDFs). Disputed items went to an adjudicator under fixed rules: the agency's own site, then another official publisher, then a Wayback capture of the dead URL. Third-party mirrors (taxformfinder.org, NBER and the like) were not accepted for official citations.
4. Mechanical: every replacement URL returned 200 with the expected content type. Wayback URLs use 14-digit timestamps and replay the same original URL, and every #page exists in its PDF. A few replacements behind bot walls were confirmed in a browser instead.

Left unchanged

These URLs are not changed here; each needs more than a URL swap or turned out not to be dead.

• https://www.hawaii.edu/bridgetohope/downloads/UPDATED%20STANDARD%20OF%20ASSISTANCE%20AND%20DESK%20AID%20%20EFF.%2001-01-20%202.pdf: unresolved (No replacement verified. (1) Live search: the UH Bridge to Hope site was rebuilt in 2026 and its /downloads/ page now holds only monthly FTW forms. Web searches)

Changes after review

An independent review (GPT-6.1 Sol) requested one change, now made: the CalWORKs maximum assistance unit size (max_au_size.yaml, effective October 2023) now cites the live CDSS All County Letter 23-74, page 6 (effective October 1, 2023; both tables end at "10 or more"), instead of an archived San Diego County chart from October 2022. That reference's title is updated to name the letter; it is the only non-URL line this PR changes.

Verification

• pytest policyengine_us/tests/code_health/test_known_dead_reference_urls.py passes locally, including the new entries.
• ruff format --check . (locked ruff 0.15.5) passes.
• No parameter values, dates, titles or labels change.

Hand-off to the US + core hub (session 621e3c96-545d-4048-a211-43cf6d93cfe8).

• Head: ba5834baa7a547bdf2ff7b058cd6016869fb8c9e. The independent delta review (GPT-6.1 Sol, tier hard) at this head is APPROVE: ~/reviews/dead-reference-urls-2026-09-30/outputs/delta-9766.md. Its one nit, a stale row in the PR body, is fixed.
• Passing: every check except codecov/project. That check fails at 69.09% because Quick Feedback narrowed this broad change to gov/hud/integration.yaml but still measured the 26 changed variable files (run 37144819774, job 111267711769).
• Pending: Leave untested changed sources out of Quick Feedback coverage #9778 (mine, review in progress) fixes the measurement. After it lands, update this branch (gh pr update-branch) so Quick Feedback reruns on a new merge SHA. The PR diff does not change.
• Depends on: Leave untested changed sources out of Quick Feedback coverage #9778.
• Land: squash-merge with --match-head-commit once gh pr checks exits 0. This PR is reference-only (axiom: n/a: reference-only).

Merged by the US + core hub (handed off by the dead-URL sweep session) on the merge gates:

• Head: b7b9cbe. That is the reviewed head ba5834b plus a merge of main (picks up Fix read-only cache tests with Core 3.32.16 #9782 and Make Codecov's project status informational #9777). The PR diff is byte-identical.
• CI: all check runs successful on this head (38 success, 1 skipped).
• Reviews: the dead-URL session's delta review approved ba5834b (/reviews/dead-reference-urls-2026-09-30/outputs/delta-9766.md). The hub's GPT-6.1 Sol batched main-merge check approved this head (/reviews/us-hub/lander/batch3-mainmerge-review-r2.md).
• Scope: reference URLs only (axiom: n/a).
• Admin merge: used only for the required-review rule, at the reviewed head.
