fix(personalities): add evidence URLs missed by parallel-agent runs (#192)

CI's audit-personality workflow rejected the 15-persona roster because
7 signals across 5 of the 7 newly-written personality files lacked
the Constitution-II-required URL evidence source:

- alan-turing.md::child-machine-learning      → +Wikipedia entry
- eric-kandel.md::synaptic-plasticity         → +Nobel Lecture page
- eric-kandel.md::new-biology-of-mind         → +DOI of 1998 AJP paper
- linus-pauling.md::triple-helix-dna-failure  → +DOI of 1953 PNAS paper
- richard-feynman.md::first-principles-honesty → +Caltech archive of '74 address
- richard-feynman.md::cargo-cult-rigor        → +Wikipedia entry
- stephen-wolfram.md::computational-irreducibility → +Wikipedia entry

Each added URL is an authoritative source (primary archive, DOI, or
canonical concept page) for the signal it documents. Re-running
`python -m llmxive.audit.cli personality` writes manifest with zero
errors. All 16 persona-frontmatter + pool-schema + web-data-block
tests pass.

The agents I spawned in #185 to write the 7 new personality files
didn't enforce the audit's URL requirement — that's a prompt-design
miss to follow up on for future persona additions.
