VS Code extension v2.1.55 fails to activate on Windows — hardcoded Linux path in build

Bug

Claude Code VS Code extension v2.1.55 crashes on activation on Windows with:

TypeError: The argument 'filename' must be a file URL object, file URL string, or absolute path string.
Received 'file:///home/runner/work/claude-cli-internal/claude-cli-internal/build-agent-sdk/sdk.mjs'

The extension was built with a hardcoded Linux CI runner path (/home/runner/work/...) embedded in extension.js:45. On Windows, Module.createRequire() rejects this path since it's not a valid local file URL.

Environment

• OS: Windows 11 Enterprise 10.0.26100
• VS Code: 1.108.1 (x64)
• Extension: anthropic.claude-code v2.1.55 (win32-x64)
• Claude CLI: 2.1.55

Steps to Reproduce

1. Install Claude Code extension v2.1.55 on Windows
2. Open VS Code
3. Extension fails to activate — all commands show "command not found"
