Require AI Figma 1.0.1 so the AI Context seeding fix is guaranteed

Problem/Motivation

The drupal/ai_figma constraint is ^1.0, which still permits 1.0.0. That release carries the AI Context seeding bug fixed in #3621167: AiFigmaInstaller wrote a grouped scope_id => [value, ...] array into the scope field, which drupal/ai_context 1.0.0-beta5 (#3586405) turned into a multi-value scope_id + value field. The resulting InvalidArgumentException was caught and logged as a warning, so the recipe reported success while no AI Context item was ever created.

VarbaseAiFigmaInstaller extends AiFigmaInstaller. Its own seeding path was fixed in #3621159 and released in 1.0.1, but the inherited parent path is fixed only in ai_figma 1.0.1. So a site resolving ai_figma 1.0.0 alongside this module still gets the silent failure.

Steps to reproduce

1. Require drupal/varbase_ai_figma 1.0.1 with drupal/ai_figma pinned to 1.0.0 and drupal/ai_context at 1.0.0-beta5 or later.
2. Apply the recipe. It reports success, the log carries Could not seed AI Context items, and no AI Context items exist.

Proposed resolution

Raise the constraint to drupal/ai_figma: ^1.0.1 so Composer cannot resolve a version without the fix.
