fix(utils,prompt): enhance error parsing and goroutine error handling

[qcserestipy]

Fix goroutine deadlocks and improve error handling in prompt and utils

Problem

• Goroutines were deadlocking when API calls failed because channels were not properly handled on error paths
• Error parsing for HTTP status codes (e.g., 403) was incomplete
• Missing error returns in functions that only returned values

Changes

• Enhanced ParseHarborErrorCode() to properly extract status codes from error messages
• Fixed GetRobotIDFromUser() to close channels and return errors on failure
• Updated GetRobotPermissionsFromUser() to handle errors through result channel instead of fataling
• All prompt functions now properly propagate errors to callers

Pull request overview

This PR fixes goroutine deadlocks and improves error handling across the codebase. The primary issue was that goroutines using channels would deadlock when API calls failed because error paths didn't properly close channels or return errors to callers.

Changes:

• Enhanced error parsing to extract HTTP status codes from various error message formats
• Fixed channel-based functions to return errors instead of deadlocking
• Standardized error messages across user and robot commands
