fix: add timeout and disable terminal prompts for remote git commands

[Pipboyguy]

Prevents indefinite hangs when accessing inaccessible repositories (non-existent, private, or requiring auth).

Changes:

• Set GIT_TERMINAL_PROMPT=0 to fail fast instead of waiting for credentials
• Add 30s timeout to remote git operations

Fixes #1077

Summary of Changes

Hello @Pipboyguy, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request addresses potential indefinite hangs during remote Git operations by implementing a 30-second timeout and disabling interactive terminal prompts for credentials. These changes enhance the robustness of Git interactions, allowing the system to fail quickly and gracefully when encountering inaccessible, non-existent, or authentication-requiring repositories, thereby improving overall system reliability and responsiveness.

Highlights

• Timeout for Remote Git Operations: Introduced a 30-second timeout for all remote Git commands (ls-remote, fetch, clone) to prevent indefinite hangs when repositories are inaccessible or slow.
• Disable Git Terminal Prompts: Set the GIT_TERMINAL_PROMPT environment variable to 0 for remote Git commands, ensuring that operations fail fast instead of waiting for user credentials interactively.

📝 Walkthrough

Walkthrough

This change adds timeout enforcement and terminal prompt suppression to Git remote operations in gitCommand.ts. A shared remoteOpts configuration combining a 30-second timeout and GIT_TERMINAL_PROMPT=0 environment variable is applied consistently to git ls-remote, fetch, and clone operations to prevent indefinite hangs on inaccessible repositories.

Changes

Cohort / File(s)	Summary
Git Remote Operation Configuration src/core/git/gitCommand.ts	Introduces GIT_REMOTE_TIMEOUT constant (30s) and gitRemoteEnv to suppress interactive prompts. Creates shared remoteOpts combining timeout and environment settings. Applies remoteOpts to git ls-remote, fetch operations (with and without remoteBranch), and clone operations to standardize remote command behavior and prevent indefinite hangs.

Code Review

This pull request correctly adds timeouts and disables terminal prompts for remote git commands to prevent hangs, which is a great improvement. However, the changes will break existing unit tests in tests/core/git/gitCommand.test.ts because the mocks for execFileAsync are no longer correct. This is a critical issue that needs to be addressed. Please update the tests to reflect the new arguments passed to execFileAsync and consider adding assertions for the new timeout and environment variables. I have also included some minor suggestions to improve code consistency by centralizing the remote command options.
