chore(standalone): remove all 12 language submodules — pure coordinator

Per the standalone-repos decision: nextgen-languages no longer vendors the
language family as git submodules; it now purely coordinates/contextualises
them. Each language remains its own standalone top-level hyperpolymath repo,
untouched.

- Removed 12 submodule gitlinks + .gitmodules: affinescript, anvomidav,
  betlang, eclexia, ephapax, error-lang, julia-the-viper, my-lang, oblibeny,
  phronesis, tangle, wokelang.
- 6a2/ECOSYSTEM.a2ml [language-repos]: now lists all 12 as referenced
  standalone repos (not vendored); note updated.
- wiki Installation: dropped the now-moot 'git submodule update' step.
- EXPLAINME: kitchenspeak is in-tree (not a submodule) — corrected.

No CI/build referenced the submodule paths (verified), so pipelines are
unaffected. KitchenSpeak stays in-tree (standalone-repo-ready).
