🧪 test(l6): rename step-02 + provider-agnostic prompt
Resolves GL !2924 (local #37).
The step name 02-onboard-local was misleading — it tests implicit reonboard FROM local-shape pre-state, paired with step-03's explicit /onboard slash-command path. The new name 02-reonboard-implicit-from-local surfaces the actual scenario.
The prompt previously hardcoded GitLab, biasing bro's provider-detection logic. New prompt asks generically (I want to push this project to a remote.) so bro exercises detection via tools/sync/backend.ts::detectAvailable() and picks gh or glab from env.
Changes:
git mvpreserves row history (old dir gone; new dir present)chain-manifest.jsonstep id=2 name + row_dir updatedEVALUATION.mdcross-refs updated- README rewritten with implicit/explicit reonboard contrast + cross-link to step 03
- Outcome scorers + setup.sh unchanged (still provider-agnostic)
Step C (dedicated fixture) deferred per !2924 plan.
Verification: bash tests/run-all.sh exit 0 on this branch (rebased onto dev with !2922 merged). All L1+L2+L3+L4 green.
pr-reviewer verdict: PASS (validation_attempts id=19).
