PhpStorm plugin install warning shown even when running from PhpStorm with plugin active

Description

When launching Claude Code from PhpStorm (via the JetBrains plugin), the startup message still shows:

Install the PhpStorm plugin from the JetBrains Marketplace

This is a false positive — the plugin is already installed and active, and the IDE connection works correctly.

Evidence

The IDE lock files in ~/.claude/ide/ correctly detect PhpStorm:

{
  "workspaceFolders": ["/path/to/project"],
  "pid": 51374,
  "ideName": "PhpStorm",
  "transport": "ws",
  "runningInWindows": false,
  "authToken": "..."
}

Expected behavior

The "Install the PhpStorm plugin" message should not appear when Claude Code detects an active PhpStorm IDE connection via the lock files.

Environment

• OS: macOS (Darwin 25.3.0)
• IDE: PhpStorm (with Claude Code plugin installed from JetBrains Marketplace)
• Claude Code: latest CLI version
