fix: replace quote delimiters with output-block tags in step-04-review

Double-quote delimiters around multi-line output template blocks are
visually ambiguous to humans (opening quote on one line, closing quote
many lines later) and confuse linters and LLM code reviewers into
filing false issues (see #1434).

A/B tested across 5 models (Opus, Sonnet, Haiku, Codex 5.2, Gemini):
removing quotes entirely causes Haiku to refuse instructions in 1/3
runs, but any explicit block delimiter works equally well. XML-style
output-block tags are the best fit: visually obvious boundaries,
self-documenting, linter-clean, and consistent with existing BMAD
XML tag conventions (step, action, check, template-output).

Relates to #1433
