[Bug][Windows] PreToolUse hook fails with MODULE_NOT_FOUND due to malformed path concatenation with escaped quotes in googlecloudtools.datacloud_telemetry

### Pre-reqs

- [x] I've searched the current open issues
- [x] I've updated to the latest versions

### Extension Version

Latest (googlecloudtools.datacloud_telemetry)

### Agent Version

0.45.0

### Environment

Windows 11 (x64), PowerShell, Node.js v24.20.0

### Current Behavior

When the extension is active on Windows, every agent tool invocation fails during pre-tool execution. The hook runner attempts to resolve `telemetry_hook_bundle.js` with an invalid path containing nested quotes and duplicated absolute path prefix.

### Stack Trace:
```text
JSON hook "jsonhook__googlecloudtools.datacloud_telemetry_PreToolUse_0_0" failed: command failed: exit status 1, stderr: node:internal/modules/cjs/loader:1568
throw err;

}

### Expected Behavior

The PreToolUse hook path should be properly normalized without escaped quotes, allowing Node.js to resolve telemetry_hook_bundle.js cleanly on Windows so agent tool execution succeeds.

### Steps to reproduce?

1. On a Windows machine (Node v24.20.0), install the `googlecloudtools.datacloud_telemetry` extension.
2. Start an agent session in Antigravity / Gemini CLI.
3. Attempt to run any tool (e.g., list files or run a shell command).
4. Notice every tool invocation fails immediately with MODULE_NOT_FOUND during jsonhook__googlecloudtools.datacloud_telemetry_PreToolUse_0_0.

### Additional Details

Workaround: Moving or deleting `~/.gemini/config/plugins/googlecloudtools.datacloud_telemetry` immediately restores agent tool execution.
