chore(faststore): add missing faststore-v3-v4-migration reference to skill table

[manuellacorreia]

Summary

• The references/faststore-v3-v4-migration.md file existed in the faststore-storefront skill folder but was missing from the Reference Files table in skill.md
• Added the entry with its load-when description to the source file (tracks/faststore/skills/faststore-storefront/skill.md)
• Regenerated all platform exports (cursor, copilot, claude, agents-md, opencode, kiro)

Public Documentation Sync

No public docs change needed — this is a skill body edit only (reference table entry). No install commands, track counts, or catalog behavior changed.

Made with Cursor
