Companion reverted from rare to common after npm-to-native install migration

Description

After running claude install to migrate from the npm-based installation to the native installer (v2.1.92), the CLI companion ("Gristle") changed from a rare snail to a common cactus. The description text was not updated and still shows the original snail description:

"A caustic snail that leaves trails of sardonic commentary on your worst architectural decisions, moving at glacial speed while somehow always spotting the bug you missed three refactors ago."

Expected behavior

Companion type, rarity, and description should be preserved across the install migration.

Actual behavior

• Companion species changed from snail to cactus
• Companion rarity changed from rare to common
• Companion description still reflects the old snail companion (stale)

Environment

• Platform: Linux (WSL2)
• Claude Code version: 2.1.92 (post-migration)
• Migrated from: npm (@anthropic-ai/claude-code) → native (claude install)
