Track Cursor and other VS Code forks separately in usage statistics

[blinkagent]

Summary

Currently, the extension sets CODER_SSH_SESSION_TYPE=vscode and --usage-app=vscode regardless of which IDE is actually being used. This means Cursor, Windsurf, and other VS Code forks are all reported as "vscode" in usage statistics.

This makes it difficult for deployment admins to understand which IDEs their users are connecting with.

Proposed Solution

Detect the IDE using vscode.env.appName and set the appropriate session type:

function getIDEName(): string {
  const appName = vscode.env.appName.toLowerCase();
  if (appName.includes('cursor')) return 'cursor';
  if (appName.includes('windsurf')) return 'windsurf';
  return 'vscode';
}

Then use this value when setting:

1. CODER_SSH_SESSION_TYPE via SSH SetEnv (in src/remote/remote.ts)
2. --usage-app flag when launching coder ssh
