docs: fix ACL template typo; hyphenate built-in trust wording

[HashClawAI]

Summary

Small documentation and comment fixes:

• Typo: seperate → separate in the ACL LaTeX template comment (skills/research/research-paper-writing/templates/acl/acl_lualatex.tex).
• Wording: Use standard hyphenation built-in trust in prose and table cells where it describes trust policy (CONTRIBUTING, skills docs). The trust level identifier builtin in backticks is unchanged.

Verification

• No code or behavior changes.
• Docs-only; optional: site build if CI requires it.
