update README

- Add dedicated ESM, CommonJS, Node.js, and browser distribution entry points.
- Add streaming support to the native Node.js SHA-256, SHA-224, and HMAC implementations.
- Add distribution contract tests and real browser Web Worker tests with Playwright.
- Add Node.js 16, 18, 20, 22, and 24 runtime tests against the packed npm artifact.

### Changed
- Refactor the implementation into environment-independent core and Node.js modules.
- Use the native Node.js `crypto` implementation for hashing and HMAC.
- Load the package version automatically when generating distribution banners.
- Export unminified ESM source directly and build only CommonJS and browser/minified distributions.
- Replace `expect.js`, NYC, Tiny Worker, and UglifyJS with Node.js assert, c8, Playwright, and Rollup/Terser.
- Build automatically before `npm pack` and `npm publish`.
- Throw error if update after finalize

### Removed
- Remove runtime CommonJS, AMD, Node.js, Web Worker, and ArrayBuffer environment switches from the core implementation.
- Remove legacy environment flags and obsolete compatibility polyfills.
- Remove the old generated `sha256.mjs` and `sha256.node.mjs` entry points.

Avioehdolla voit määrätä, että puolet kuolleen puolison omaisuudesta siirtyy verovapaasti leskelle.\n\nVoit halutessasi hyödyntää seuraavia tietoja tekstin muotoilussa persoonallisemmaksi: Käyttäjällä on kumppani nimeltä PARTNER_NAME. Käyttäjällä on suurperhe. Käyttäjällä on lapsiperhe.\n\nPuhuttele käyttäjää siihen sävyyn että tiedät jo mitä käyttäjä haluaa, koska hän on kertonut toiveistaan, ja niiden perusteella tehty suositus on ilmiselvä. Joten älä käytä epävarmoja ilmaisuja kuten "halutessasi", vaan kirjoita itsevarmoilla ilmaisuilla kuten "koska haluat". Älä tee oletuksia käyttäjän sukupuolesta, emme tiedä onko hän mies vai nainen. Älä käytä sanaa jälkikasvu, puhu ennemmin lapsesta tai lapsista riippuen onko lapsia yksi vai useampia. Älä puhuttele käyttäjää ensimmäisessä persoonassa, käytä ennemmin passiivimuotoa. Tekstin sävyn tulisi olla neutraalin asiallinen, ei melodramaattinen eikä leikkisä. Pysy totuudessa, älä keksi uusia seikkoja yllä listattujen lisäksi. Viittaa ihmisiin nimillä silloin kun se on mahdollista. Tekstin tulisi olla vain muutaman lauseen mittainen. Älä siis kirjoita pitkiä selityksiä äläkä kirjoita listoja.

Suositus perustuu seuraaviin seikkoihin:\n\nSeikka 0: Avioehdon tekeminen on verohyötyjen vuoksi suositeltavaa, koska olet ilmaissut että haluat kuoleman tapauksessa turvata ensisijaisesti aviopuolisosi asemaa (ennemmin kuin lasten asemaa). Avioehdolla voit määrätä, että puolet kuolleen puolison omaisuudesta siirtyy verovapaasti leskelle.\n\nVoit halutessasi hyödyntää seuraavia tietoja tekstin muotoilussa persoonallisemmaksi: Käyttäjällä on kumppani nimeltä PARTNER_NAME. Käyttäjällä on suurperhe. Käyttäjällä on lapsiperhe.\n\nPuhuttele käyttäjää siihen sävyyn että tiedät jo mitä käyttäjä haluaa, koska hän on kertonut toiveistaan, ja niiden perusteella tehty suositus on ilmiselvä. Joten älä käytä epävarmoja ilmaisuja kuten "halutessasi", vaan kirjoita itsevarmoilla ilmaisuilla kuten "koska haluat". Älä tee oletuksia käyttäjän sukupuolesta, emme tiedä onko hän mies vai nainen. Älä käytä sanaa jälkikasvu, puhu ennemmin lapsesta tai lapsista riippuen onko lapsia yksi vai useampia. Älä puhuttele käyttäjää ensimmäisessä persoonassa, käytä ennemmin passiivimuotoa. Tekstin sävyn tulisi olla neutraalin asiallinen, ei melodramaattinen eikä leikkisä. Pysy totuudessa, älä keksi uusia seikkoja yllä listattujen lisäksi. Viittaa ihmisiin nimillä silloin kun se on mahdollista. Tekstin tulisi olla vain muutaman lauseen mittainen. Älä siis kirjoita pitkiä selityksiä äläkä kirjoita listoja. Tiivistä oleellinen tieto lyhyeksi ja persoonalliseksi tekstiksi.'
