Codex task: normalize TranslationLab functional lab manifest, validation, and release-dry-run skeleton

[mdheller]

Mission

Normalize translationlab as the SociOS lab for translation, multilingual alignment, terminology memory, speech translation, and cross-language retrieval tuning.

This issue is designed for a Codex agent because it must align with NLPLab, EmbeddingLab, Holmes, and Prophet Core Query. Keep the change bounded and open a PR.

Scope

Add a minimal lab skeleton without pulling heavy model dependencies:

• docs/LAB_SURFACE.md
• docs/PROPHET_INTEGRATION.md
• examples/functional-service.json
• examples/eval-fixture.json
• tools/validate_examples.py
• Makefile
• optional .github/workflows/validate.yml

Required Make targets

make validate
make emit-service-manifest
make emit-eval-fixture
make release-dry-run

Acceptance criteria

• make validate passes with no network or model downloads.
• make emit-service-manifest writes or prints the functional service manifest.
• make emit-eval-fixture writes or prints the eval fixture.
• Docs explain integration with holmes, nlplab, embeddinglab, functional-model-surfaces, and prophet-platform.

Do not

• Do not download or vendor translation models.
• Do not vendor corpora or datasets.
• Do not implement real training jobs.
• Do not make SourceOS responsible for model promotion.
