[Bug] Auto-update fails with npm ENOTEMPTY rename error

Bug Description
I keep getting auto-update errors. When I quit and attempt to do the update myself, it fails because of some kind of corruption of the global npm package install. I then have to manually delete the entire package and do a fresh install.

This is the message I get in the Claude Code terminal at the bottom in red text:

✗ Auto-update failed · Try claude doctor or npm i -g
@anthropic-ai/claude-code 

This is the error I get when I exit and attempt to update manually:

❯ npm i -g @anthropic-ai/claude-code
npm error code ENOTEMPTY
npm error syscall rename
npm error path /Users/<username_redacted>/.nvm/versions/node/v20.19.4/lib/node_modules/@anthropic-ai/claude-code
npm error dest /Users/<username_redacted>/.nvm/versions/node/v20.19.4/lib/node_modules/@anthropic-ai/.claude-code-0ePLndiR
npm error errno -66
npm error ENOTEMPTY: directory not empty, rename '/Users/<username_redacted>/.nvm/versions/node/v20.19.4/lib/node_modules/@anthropic-ai/claude-code' -> '/Users/<username_redacted>/.nvm/versions/node/v20.19.4/lib/node_modules/@anthropic-ai/.claude-code-0ePLndiR'
npm error A complete log of this run can be found in: /Users/willd/.npm/_logs/2025-09-10T00_42_19_467Z-debug-0.log

It only works again if it rm -rf the claude-code package directory and then run a fresh install.
