fix: align Flutter sub-package runanywhere dep constraint with release version

CodeRabbit P-Major flagged (correct): the runanywhere_genie / llamacpp /
onnx Flutter sub-packages were bumped to 0.19.12 but still declared
`runanywhere: ^0.16.0` as their core dependency. pub would resolve the
core as 0.16.0 from pub.dev — missing every API added since — making
the newly-released backend packages unusable for consumers.

Fix:
- Update the three sub-packages' runanywhere caret constraint to
  ^0.19.0 (MAJOR.MINOR floor of the current release).
- Teach sync-versions.sh to keep this constraint aligned with the
  release version automatically on future bumps, so this can't
  drift again.
