Fix logo alt text, exclude upstream test harness, record overrides

Three follow-ups from verifying the v1.1 build:

- `_includes/header.liquid`: the logo `alt` chained `site.title | default: ... |
  append: site.middle_name | append: site.last_name`, so with a non-blank
  `site.title` it appended the name parts anyway and rendered "Sustainable Urban
  Systems Lab Urban Systems Lab". Now it picks one branch or the other. This bug
  predates the migration; fixing it here since the file was being rewritten.

- `_config.yml`: exclude `test/`. v1.1 ships a Playwright/integration harness in
  the starter but does not exclude it, so the specs and shell scripts were being
  published to the live site.

- `.al-folio-overrides.yml`: records the 8 intentional overrides with the upstream
  checksums they were reviewed against, so `al-folio upgrade overrides audit` can
  flag drift on future gem bumps.

Verified in Docker (ruby 3.3.12): jekyll build clean, `al-folio upgrade audit`
reports 0 blocking findings, and the resolved gems include al_img_tools 1.0.3,
al_math 1.0.2 and al_folio_distill 1.0.3 — the three carrying the v1.1 security
fixes. Swiper resolves to 12.1.2 with matching SRI hashes.
