[BUG] Marketplace refresh fails on macOS - uses hardcoded /home/claude path instead of actual HOME

What's Wrong?

When Claude Code attempts to refresh the official marketplace on macOS, it fails because it uses /home/claude as the home directory path instead of the actual user's home directory (/Users/username).

What Should Happen?

Claude Code should use the correct macOS home directory path (/Users/username/.claude/plugins/marketplaces/...) when refreshing marketplaces.

Error Messages/Logs

Failed to refresh marketplace 'claude-plugins-official': Failed to clone marketplace repository: fatal: could not create leading directories of '/home/claude/.claude/plugins/marketplaces/claude-plugins-official': Operation not supported

Steps to Reproduce

1. Install Claude Code via npm-local on macOS
2. Run Claude Code
3. Observe the marketplace refresh error on startup (or run /plugins marketplace refresh)

Is this a regression?

Additional Information

Diagnostics:

Currently running: npm-local (2.1.1)
Path: /Users/username/.local/share/mise/installs/node/24.11.0/bin/node
Invoked: /Users/username/.claude/local/node_modules/.bin/claude
Config install method: local
Auto-updates: enabled
Search: OK (vendor)

Root Cause Analysis:

The HOME environment variable is properly set in the user's shell (HOME=/Users/username), but when commands are run inside Claude Code's sandbox, HOME appears to be empty or unset.

When the marketplace refresh code can't find HOME, it falls back to a hardcoded /home/claude path - which is a Linux-style path that doesn't exist and can't be created on macOS.

Claude Code should use os.homedir() in Node.js or properly inherit the HOME environment variable from the parent shell.
