fix: correct doc drift in agents, security, conduct, contributing (#714)

- AGENTS.md: Python floor is >=3.11 (tested 3.11-3.14), not >=3.13
- SECURITY.md + CODE_OF_CONDUCT.md: use canonical contact email
  quangminh2402.dev@gmail.com (matches sibling n24q02m repos)
- CONTRIBUTING.md: clarify only feat:/fix: prefixes are accepted
  (enforced by commit-msg hook), not all Conventional Commit types
