Claude full-chain coverage looks on track (new helper support + new Playwright spec).

Requested changes:

• Please wire CLAUDE_INIT_IMAGE through the suite runner (scripts/run-pipeline.sh) so the README-documented override actually works when running via devspace run test-e2e.

Non-blocking:

• Consider making the “no spans” failure message SDK-aware (it currently references codex).
• Consider switching Refs #60 → Closes #60 to auto-close on merge.

Re-review: changes requested are addressed.

• CLAUDE_INIT_IMAGE is now forwarded through scripts/run-pipeline.sh, so the documented override works with devspace run test-e2e.
• The “no spans” failure message is now SDK-aware and points to the correct init image env var.
