Srt Booking

This wraps the SRTrain Python library to search, reserve, and cancel SRT train tickets in Korea. It pulls credentials from environment variables or a local secrets file, searches available trains between stations, shows you the options with pricing and seat availability, then reserves once you pick one. The workflow is careful about side effects: it always lists candidates before booking anything. Useful if you're building a Korean travel assistant and want seat booking without touching payment. Won't help with KTX or full checkout flows, and it keeps retry logic conservative to avoid hammering the account. Clean separation between read and write operations, which matters when you're dealing with real reservations.
