Fixes from PR #2448 review:
- PPA claim: removed "$1.5B" overclaim from title (evidence only confirms >$1B), removed broken SMR wiki link
- SPARC manufacturing: downgraded likely→experimental, narrowed title to "pancake production" not "fusion manufacturing"
- Helion/CFS comparison: broadened to three-horse race (added TAE $1.79B), title no longer frames as two-horse
- Magnet platform: unchanged (no issues flagged)
