Add Cursor and Windsurf as recognized IDE session types for usage tracking #21361

Summary

Currently, the allowed session types for IDE tracking are limited to vscode, jetbrains, ssh, and reconnecting-pty. To properly track usage of VS Code forks like Cursor and Windsurf, we need to add them as recognized session types.

This will help deployment admins better understand which IDEs their users are connecting with.

Changes Required

1. MagicSessionType in agent/agentssh/agentssh.go

Add new session type constants:

MagicSessionTypeCursor   MagicSessionType = "cursor"
MagicSessionTypeWindsurf MagicSessionType = "windsurf"

Update extractMagicSessionType() to recognize these values.

2. UsageAppName in codersdk/workspaces.go

Add new usage app names:

UsageAppNameCursor   UsageAppName = "cursor"
UsageAppNameWindsurf UsageAppName = "windsurf"

Update AllowedAppNames slice.

3. cli/ssh.go

Update getUsageAppName() to include the new app names in allowedUsageApps.

4. coderd/workspaces.go

Add cases in the switch statement for the new app names to track session counts.
