Release v1.4.3

Fixed

• Cross-region session + device discovery reliability (pyvesync parity): normalize hydrated sessions and retry the device list call on cross-region responses using the server-provided region when available.
• Token invalidation recovery: treat -11001000 as token expired/invalid and perform a one-time re-login + device list retry.

Changed

• Added parity notes/diagnostics clarifying pyvesync auth/device discovery payload differences.
