fix: normalize phase numbers in stats Map to prevent duplicate rows

When ROADMAP.md uses unpadded phase numbers (e.g. "Phase 1:") and
the phases/ directory uses zero-padded names (e.g. "01-auth"), the
phasesByNumber Map held two separate entries — one keyed "1" from the
ROADMAP heading scan and one keyed "01" from the directory scan —
doubling phases_total in /gsd-stats output.

Apply normalizePhaseName() to all Map keys in both the ROADMAP heading
scan and the directory scan so the two code paths always produce the
same canonical key and merge into a single entry.

Closes #2195
