AutoStory M10 FireRed end to end with options #145

• Scope: table rows that branch on a choice: the other two starters (rival teams change), gift picks such as the Mt. Moon fossil, and optional tasks (extra catches, items, side areas) a run can switch on.
• PRs: about 4–6, after M8.
• Done when: a new game → Hall of Fame run passes with each starter, and each optional task passes 3/3 in its segment.
