v0.8.5 — README refresh (HACS pick-up tag)

Korean infant/child reference data integration for Home Assistant.
Install via HACS → Custom repositories → `https://github.com/redchupa/kr_baby_kit\` (Category: Integration).

Why this release exists

v0.8.4 already shipped two README fixes on main:

1. The shields.io License badge was removed (broken on HACS-over-HTTP setups due to adblock filters matching `license` URL patterns).
2. The "등록 후 대시보드에서 보이는 것들" section was synced to the v0.8.4 underscore-only friendly-name form.

But HACS users fetching the latest tag kept seeing the older v0.8.4 README (with the broken badge). v0.8.5 is purely a tag bump so HACS re-fetches the current README.

What changed

• README: License badge dropped, entity-name listing already in v0.8.4 form
• `manifest.json` version bump only — no code, schema, or behavior changes
• `unique_id`, sensor values, attribute payloads, on-disk records all unchanged from v0.8.4

After upgrading

HACS → Integrations → 한국 영유아 키트 카드의 ⋮ → UPDATE 또는 REDOWNLOAD. README의 License 배지 자리가 사라지고 entity 이름이 `키_입력`, `백분위_키_1퍼센트는_가장_큼`, `양극단_주의_BMI` 형식으로 노출됩니다.
