Improve code quality

[Chandraveersingh1717]

Fix a few type and code quality issues:

• Corrected the Branches interface to use string[] instead of a single-element tuple [string]
• Replaced loose equality (==) with strict equality (===) in inspectByName
• Fixed ready() to return the boolean response body (res.data) instead of checking the HTTP status code
• Replaced the infinite loop (for(;;)) in waitFor with a clearer while loop
