Mastra Factory Adds Custom Skills

This is a small feature with outsized leverage: configurable agent behavior is what separates a demo coding agent from an operational software factory.

• –Skills can capture security reviews, testing rules, release procedures, and domain conventions.
• –Repo-native files make customization versionable, reviewable, and reproducible.
• –No UI management or listing yet, so discovery and hot reload remain unfinished.
• –The feature moves customization from prompt tweaking toward maintainable context engineering.
