test: add 3 E2E smoke tests for base branch detection

- /review: verifies Step 0 detection + git diff against detected base - /ship: truncated dry-run (Steps 0-1 only, no push/PR), asserts no destructive actions - /retro: verifies default branch detection for git log queries Covers the {{BASE_BRANCH_DETECT}} resolver path (review), the ship template's dual abort check, and retro's inline detection pattern.
