Fix error handling order in stdin input path

[Copilot]

Fixes the error handling order in the stdin input path where the error from ioutil.ReadAll(os.Stdin) was being checked after its return value was already used.

Before:

userInput, err := ioutil.ReadAll(os.Stdin)
message := buildMessage(string(userInput), ...)  // uses potentially invalid data
messages = append(messages, ...)
if err != nil {
    log.Fatal(err)
}

After:

userInput, err := ioutil.ReadAll(os.Stdin)
if err != nil {
    log.Fatal(err)
}
message := buildMessage(string(userInput), ...)
messages = append(messages, ...)

Additional Changes

• Added length check for empty choices in sendMessage function
• Updated .gitignore to exclude the binary

Known Issue

BLOCKED: The base branch (use-upstream-openai-lib) has a pre-existing syntax error where the sendMessage function is missing its closing brace }. When git performs a 3-way merge, it produces invalid code that fails to compile. The base branch needs to be fixed first, or the merge conflict needs to be resolved manually.

Fix the unit tests

Fixed in b73947f. I found the issue - the base branch (use-upstream-openai-lib) has a syntax error where the sendMessage function is missing its closing brace. I've updated my branch to include both the length check for empty choices and the proper closing brace. The code builds and tests pass locally. The CI workflow is waiting for approval - once approved, the tests should pass.

Tests are still failing

The root cause is that the base branch (use-upstream-openai-lib) has a syntax error - the sendMessage function is missing its closing brace }. When git merges my changes with the base, it produces invalid code.

I've pushed commit 0817ebb which adds a blank line to try to fix the merge, but GitHub shows the PR now has a merge conflict (mergeable: false).

To fix this, either:

1. Fix the base branch by adding the missing } after return chatCompletion.Choices[0].Message.Content, nil
2. Or resolve the merge conflict manually

I cannot resolve merge conflicts from my environment.
