Task-oriented guides

These guides connect the public API to the operating constraints that tend to matter after a prototype becomes a service. They describe the current 0.1.x Alpha behavior; use the generated API reference for individual symbols and development notes for the complete local command reference.

Updates and recovery explains queue limits, persistent cursors, difference recovery, handler ordering, and cancellation.
String-session migration covers native, Telethon, and Pyrogram session strings and the import safety checks.
Production operation covers ownership, shutdown, resources, and redaction.
Observability covers logging, metrics, and resource snapshots.
Proxies and datacenters explains transport proxy URLs and the separation between primary and media DC state.
Event-loop ownership covers application-owned loops, runners, and the legacy installer.
Troubleshooting gives targeted recovery paths for common startup, update, proxy, native, and test-gate failures.
Native extension diagnosis explains the Rust extension probe and the Python fallback boundary.
Performance and benchmarks explains what the benchmark commands measure and which results are comparable.

Security and media details remain in their canonical pages: session storage and credentials and media transfers.
