[Bug] Plugin hooks fail on Windows with spaces in username path

Bug Description
Bug Report: Plugin Hooks Fail on Windows with Spaces in Username

Environment:

• OS: Windows
• Username path: C:\Users\Burak Demir (contains space)
• Claude Code version: 2.0.76
• Installation method: native

Issue:
Claude Code fails to start plugin hooks when the Windows username contains spaces.

Error messages on startup:
SessionStart:startup says: Plugin hook error: 'C:\Users\Burak' is not recognized as an internal or external command,
operable program or batch file.
Error: Cannot find module 'C:\Users\Burak'
at Module._resolveFilename (node:internal/modules/cjs/loader:1420:15)
...
code: 'MODULE_NOT_FOUND'

The path is being split at the space character, treating "C:\Users\Burak" as the command and "Demir" as a separate argument.

Affected plugins:

• superpowers
• double-shot-latte
• learning-output-style
• episodic-memory

Root cause:
Plugin hook scripts (.sh and .cmd files) are not properly quoting paths when executing on Windows with spaces in the username.

Workaround:
Temporarily renaming the plugins folder resolves the issue, but disables all plugins.

Expected behavior:
Plugin hooks should work correctly regardless of whether the Windows username contains spaces.

Suggested fix:
All path references in plugin hook execution should be properly quoted or escaped for Windows compatibility.
