fix(docs): correct research citations and 3 dead URLs (F-3)

Verified every research citation in README.md and SKILL.md against its
primary source. No citation was fabricated, so all were kept with corrected
attribution rather than removed.

- SKILL.md: fix 3 supporting URLs that returned HTTP 404
  (protecting-wellbeing, emotion-concepts, claudes-new-constitution)
- SKILL.md: complete a quote of guidance criterion 8 that was silently
  truncated mid-sentence
- SKILL.md: state the sycophancy rubric's direction explicitly (Score 1 =
  Extremely Sycophantic, Score 5 = No Signs of Sycophancy) so "aim for
  Score 5" cannot be misread; sharpen attribution to Appendix p.9
- README.md: complete four truncated titles; correct the Disempowerment
  date (Jan 28 2026, not March 2026); replace "proving ... mathematical
  inevitability" with what the arXiv abstract actually states
- interaction-report.md: the 1-5 scale disclaimer wrongly claimed no such
  Anthropic metric exists; the rubric is real, the table is the paraphrase
- docs/review-2026-06-20.md: full verification log with sources

Constitution quotes, the Score 5 wording, the 11-criteria count and the
page-2 reference all verified correct and left unchanged.

Tests: 257/258 (the 1 red is the known perf wall-clock flake).
