* fix(#1551): match dash-separated milestone phase IDs in roadmap analyze checklist scan
The checklist scanner in cmdRoadmapAnalyze allowed only a dot separator
(?:\.\d+)* while the detail-heading scanner allows [.-], so milestone-prefixed
IDs (1-01) truncated at the dash (-> 1) and reported phantom missing detail
sections on every well-formed milestone roadmap. Widen the char class to
(?:[.-]\d+)* to match the detail scanner and the shared phaseMarkdownRegexSource
helper.
Fixes#1551
