fix: add conditional configuration for GOOSE_BIN_DIR in PATH

[allen0099]

Summary

This pull request introduces a conditional check to the download_cli.sh script, improving how the script handles adding GOOSE_BIN_DIR to the user's PATH. The main change is that the script now respects a CONFIGURE flag, which allows users to skip interactive configuration and receive manual instructions instead.

Enhancements to PATH configuration logic:

• Added a check for the CONFIGURE environment variable to determine whether to prompt the user interactively or simply show manual instructions for adding GOOSE_BIN_DIR to the PATH.
• If CONFIGURE is not enabled, the script now displays a message indicating that configuration is disabled and instructs the user to add GOOSE_BIN_DIR manually.

Pull request overview

This PR improves the download_cli.sh script by adding conditional handling for the CONFIGURE environment variable when prompting users to add GOOSE_BIN_DIR to their PATH. This aligns the PATH configuration behavior with the existing goose configure step (line 290), allowing non-interactive installations to skip prompts entirely.

• Wraps the interactive PATH configuration prompt in a CONFIGURE check
• Displays a simple message when configuration is disabled, prompting manual PATH setup

[Copilot]

When CONFIGURE is disabled, users don't receive instructions on how to manually add GOOSE_BIN_DIR to their PATH. Consider showing the same instructions as choice "2" (lines 341-344) so users know the exact command to run.
