chore(submodules): bump pointers for security conformance fixes

Bump submodule pointers to pick up the fix(security) removal of
`eval` from conformance/run_conformance.sh across 4 language repos,
plus the my-lang hygiene fixes commit:

- betlang:    e3eaff5..646b500
- error-lang: 10cb351..663f346
- my-lang:    506c0ae..0d46972
- phronesis:  c3455cc..7e3142f
- tangle:     8ce7be7..3b39fb5

Each of these bumps also pulls in legitimate upstream work that was
already on the respective submodule's main branch (dependency bumps,
CRG recipes, documentation rewrites, etc.) as a side effect of the
rebase.

Still outstanding after this commit:
- wokelang: on feat/e2e-validation-tests branch, not main.
  Conformance fix deferred until branch lands on main.
- affinescript submodule pointer: pre-existing in-progress work,
  deliberately NOT bundled with this commit.

Resolves 5 Critical panic-attack CommandInjection findings.
