v0.5.0

0.5.0 - 2026-08-16

Added

• packs/smoke, a zero-dependency deployment check pack that runs on an
  in-memory SQLite database (no server, no driver, no seed data):
  smoke_ping, smoke_get_server_status, smoke_fortune and
  smoke_horoscope. config/smoke.yaml runs it through the pack allowlist,
  tests/test_pack_smoke.py exercises every tool and stays green in CI, and
  docs/smoke.md documents the deployment checks and a failure guide.

Changed

• Unit tests now run on Python 3.12 and 3.14 in CI; Python 3.14 is advertised
  in package metadata.
