Windows: Hook relative paths with `..` intermittently fail to resolve

Description

On Windows, hooks configured in .claude/settings.json with relative paths containing .. intermittently fail to resolve. The .. appears to be dropped or not resolved, causing the path to treat the target as a subdirectory instead of a sibling.

Reproduction

Settings.json hook config:

{
  "Stop": [{
    "hooks": [{
      "type": "command",
      "command": "node \"../skimmer-ai-orchestration/.claude/scripts/hooks.mjs\" session-end",
      "timeout": 30000,
      "continueOnError": true
    }]
  }]
}

Expected path resolution (CWD = C:\src\skimmer\skimmer-eng-automation):

C:\src\skimmer\skimmer-ai-orchestration\.claude\scripts\hooks.mjs

Actual path in error:

C:\src\skimmer\skimmer-eng-automation\skimmer-ai-orchestration\.claude\scripts\hooks.mjs

The .. is not resolved — the sibling repo path is treated as a subdirectory.

Notes

• Running the same command from bash in the same CWD resolves correctly
• Happens intermittently (not every time)
• Affects Stop, PreToolUse (Write/Edit), and PostToolUse hooks — all configured with the same relative path pattern
• continueOnError: true makes it non-blocking but the error output is visible
• Quoting the path (added in our project setup) did not fully resolve the issue

Environment

• Windows 11 Home 10.0.26200
• Claude Code CLI (latest)
• Node.js (latest LTS)
• Shell: bash (Git Bash on Windows)
