Expose every order component as its own entity and prepare for release

Each cost line is now an entity rather than an attribute: subtotal, box price,
add-ons, tax and delivery fee, plus a total and free-delivery-remaining for the
open order, a delivery-day sensor, and a binary sensor that turns off at the
cutoff. Entities share a base class and declare a scope, so a description
states only the field it reads.

Also parses the driver tip, Bounty savings and the free-delivery threshold. The
threshold is carried across orders because the progress bar only renders on
carts that have not met it.

Adds LICENSE, hacs.json, a CI workflow, a pre-publish audit script, and a test
that cross-checks every entity's translation_key against both translation
files. Manifest URLs now point at GitHub rather than a private forge.

+## [0.3.0] - 2026-08-03
+
+Prepared for public release as a HACS custom repository.
+
+### Added
+
+- Every cost component is now its own entity rather than an attribute:
+  subtotal, box price, add-ons, tax, and delivery fee for the next delivery,
+  plus a total and free-delivery-remaining for the open order.
+- `binary_sensor.fresh_harvest_order_open`, which turns off when the cutoff
+  passes — the last moment to change the box.
+- `sensor.fresh_harvest_delivery_day`.
+- Parsing for the driver tip, potential Bounty savings, and the free-delivery
+  threshold, with the threshold carried across orders because the progress bar
+  only renders on carts below it.
+- `LICENSE` (MIT), `hacs.json`, and a CI workflow running hassfest, the HACS
+  action, and the test suite.
+- `tests/test_translations.py`, which cross-checks every entity's
+  `translation_key` against both translation files and fails on an orphan or a
+  missing name.
+
+### Changed
+
+- Entities share a `FreshHarvestEntity` base and declare a `scope`
+  (`account`, `next_order`, `open_order`), so a description states only the
+  field it reads instead of repeating None handling.
+- `manifest.json` documentation and issue-tracker URLs now point at GitHub;
+  they previously pointed at a private forge that no installer could reach.
+- Fixture cart identifiers replaced with placeholders.
