fix: stop manual spinners in link, init, and repo commands on Ctrl+C …

[Huerte]

Type

• Bug fix
• New feature
• Documentation
• Refactor / internal

Changes

• ssh_utils.py: wrapped _get_cached_ssh_response and _get_ssh_response inside check_connection with a KeyboardInterrupt handler so the manual SSH check spinner stops cleanly if the user hits Ctrl+C during gitgo link.
• repo.py: added a KeyboardInterrupt handler to repo_operation to ensure the repository creation spinner stops properly.
• init.py: added KeyboardInterrupt handlers to both the download and extraction phases of _download_and_extract_template so the template fetching spinner halts cleanly on interrupt.

Checklist

• Tested locally and changes work as expected
• CHANGELOG.md updated under [Unreleased] (Note: Updated directly in 1.10.3 for patch republish)
• README.md updated (if a command was added or changed)
• Tests added or updated (if applicable)
• No existing commands are broken (if they are, describe the impact above)
