Pull Request Overview
This PR adds PowerShell support for Windows environments by creating keys_upload.ps1, a comprehensive port of the existing keys_upload.sh script. The PowerShell version provides equivalent functionality while adapting to Windows-specific credential management, SSH client behavior, and console capabilities.
Key changes:
- Full feature parity with bash version including smoke test mode, SSH host discovery, and credential upload
- Windows-native credential storage using Windows Credential Manager instead of macOS Keychain
- Platform-specific adaptations for SSH configuration parsing, remote script execution, and color output

The indexing logic is incorrect. $Keys.Keys[$i-1] will fail because $Keys.Keys returns key names, not an indexed array. The loop should iterate through the actual keys and hosts instead of using array indexing on the hashtable keys.

The Get-Credential cmdlet will prompt the user for credentials interactively, which is not the intended behavior for retrieving stored credentials from Windows Credential Manager. This should use the Windows Credential Manager API directly instead of prompting for user input.

In smoke test mode, Get-RemoteKeychainPassword returns $true immediately but still requests a password from the user for normal mode even when in smoke test. The password request should be skipped entirely in smoke test mode since line 568-570 shows the function returns early for smoke tests.

The remote keychain password is passed as a plain text environment variable through SSH, which could be visible in process lists or logs. Consider using a more secure method for password transmission.

API keys and tokens are passed as plain text environment variables through SSH, which could be visible in process lists or logs. This creates a security risk where sensitive credentials might be exposed.
