Title: Custom pet is visible on Windows but does not animate; logs show malformed spritesheet path parsing

Environment:

• Codex Desktop
• Windows
• Local logs show app-server version 0.131.0-alpha.9

Observed behavior:

• Custom pets are correctly installed under: C:\Users\Administrator\.codex\pets\<pet-id>\
• The pet is visible in the UI and can be selected
• However, it never animates and appears static
• I already tried:
  • switching to another pet and switching back in Settings -> Appearance -> Pets
  • Hide pet / Show pet
  • fully quitting and restarting Codex Desktop
• None of the above fixed it

What I verified:

• pet.json is valid
• spritesheet.webp exists
• spritesheet.webp is 1536x1872
• it has transparency
• the animation atlas is populated and not blank
• this is not limited to one pet; at least two custom pets show the same behavior

Relevant log clue:

• Failed to watch open file
• the spritesheet path appears malformed in logs, for example: /C:/Users/Administrator/Documents/Codex/2026-05-21/install-this-petdex-pet-by-running-3/C:UsersAdministrator.codexpetslulu-capybaraspritesheet.webp

Suspicion:

• this does not look like a broken pet asset
• it looks more like a Windows-specific custom pet path parsing / file watch / animation initialization issue
