v0.6.0-beta

Beta of the v0.6.0 improvements (PR #114). Pre-release — enable "show beta versions" in HACS. Restart Home Assistant after updating.

What to test

• Weather sensors (temperature, humidity, condition) appear on the Plant device.
• Reconfigure the entry (change email/"plus" without removing it).
• UI shows Spanish when Home Assistant language is es; Portuguese for pt/pt-BR.

Included

• CI now runs the test suite; strings.json added.
• API robustness: 4xx responses no longer retried; authentication errors keep their type (re-auth fires correctly).
• Devices link to the Intelbras portal; notification timer cancels on shutdown.
• 34 tests green; ruff, hassfest, HACS pass.

Notes

• Built from the PR #114 branch (not yet merged).
• Not declaring quality_scale, no repairs, no records backfill (see PR for rationale).
