I/O and native services

Choose the guide for the service you are using:

• Local I/O — stdout, stdin, files, and file paths.
• Networking and signals — blocking and non-blocking TCP, polling, UDP, signals, and TLS.
• Databases — SQLite3, PostgreSQL, and MySQL.
• Time — construction, parsing, formatting, timezones, arithmetic, comparisons, durations, and monotonic time.
• Processes — completed commands and live subprocess handles.
• JSON — JSON.stringify and JSON.parse.

All native-resource objects require explicit cleanup where their topic guide documents close(). Use ensure when a resource must be released after an exception.
