v0.2.2

Retry + Python 3.10+ floor

New

• Sync and async clients now retry transient upstream failures (502/503/504 or connect/read errors) up to 3 times with full-jitter exponential backoff (500ms base → 4s cap). Shields SDK users from brief API-server restart windows. See SHA-1994.

Breaking

• Dropped Python 3.9 support. 3.9 reached EOL 2025-10. The package had declared 3.9 support but models.py uses PEP 604 union syntax (int | float) which Pydantic evaluates at runtime and which has always failed on 3.9. Requires Python 3.10+.

Internal

• USER_AGENT bumped to sharpapi-python/0.2.2.
