Cut the README down to an introduction and links

Running ihasmail is covered on docs.ihasmail.org, now including the
published image, the admin URL and BASE_PATH. Architecture, the mock's
switches and version numbers move to CONTRIBUTING.md, and 0.16.21's
client-visible changes to KNOWN-ISSUES.md. The Gmail comparisons go.

## Code of Conduct
@@ -30,7 +30,7 @@ Before opening a new issue, please search [existing issues](https://github.com/C
Open an issue describing:
- The problem you're trying to solve (not just the solution)
- How it fits with ihasmail's JMAP-only, Gmail-style design philosophy
- How it fits with ihasmail's JMAP-only, nothing-to-persist design
- Any relevant JMAP RFC references (RFC 8620, RFC 8621) if the feature touches protocol behavior
For larger changes, please open an issue to discuss the approach **before** submitting a pull request — this saves everyone time if the direction needs adjusting.

2. Point your local instance at a running Stalwart Mail Server (a test/dev instance is strongly recommended — do not develop against a production mailbox).
3. Follow the setup instructions in the repository's `README.md` for installing dependencies and running the app locally.
2. Point your local instance at a running Stalwart Mail Server (a test/dev instance is strongly recommended — do not develop against a production mailbox), or use the built-in mock below.
3. Install and run, as below.
4. Verify your changes don't break existing JMAP calls by exercising core flows: login, list/read mail, send, search, and folder/label operations.
Requirements: Node ≥ 20.19 (26 recommended), npm ≥ 10.
```bash
npm install
npm run dev # real Stalwart (STALWART_URL in .env) — server :8080, Vite :5173
npm run dev:mock # built-in mock Stalwart ([email protected] / demo), mock on :8788
npm run dev:mock:no-future-release # mock that advertises FUTURERELEASE and drops every hold
npm run typecheck # tsc for both packages
npm test # vitest (web) + node:test (server)
npm run build # web/dist + server/dist
npm start # serve the production build
```
Open http://localhost:5173 in dev, or http://localhost:8080 for the production
build.
#### Architecture
```
browser ──(same-origin /api/*)──► ihasmail server (Node + Hono) ──(JMAP over HTTPS)──► Stalwart
React SPA • session cookie ⇄ Basic auth
JMAP client + stores • /api/jmap, /api/blob, /api/upload, /api/events (SSE), /api/image
```
- `web/` — Vite + React 19 + TypeScript SPA. `src/jmap` (client, push, types), `src/store` (zustand: session, mail, compose, contacts, calendar, files, sieve, settings), `src/views`, `src/lib` (sanitiser, search parser, Sieve codec, locale-aware dates, vCard, …).
- `server/` — Node/Hono backend: authenticates against Stalwart's JMAP session endpoint, seals the credentials with a key derived from the cookie secret, proxies JMAP/blob/SSE, serves the SPA under a strict CSP. `src/mock/` is an in-memory fake Stalwart for development and demos.
Capabilities used: `core`, `mail`, `submission`, `vacationresponse`, `sieve`,
`contacts`(+`parse`), `calendars`(+`parse`), `principals`(+`availability`),
`quota`, `blob`, `filenode`, EventSource push, plus Stalwart's own
`urn:stalwart:jmap`. Features degrade gracefully when one is missing.
#### The mock
An in-memory fake Stalwart 0.16 — enough JMAP to develop and demo against
without a real mailbox. It reproduces the things a naive fake would get wrong,
because each cost a live debugging session: `urn:stalwart:jmap` advertised
**per-account** rather than session-level, identity signatures capped at 2047
**bytes**, and `CalendarEvent/set` speaking Stalwart's vocabulary rather than
RFC 8984's.
| Switch | What it does |
| --- | --- |
| `MOCK_NO_FUTURE_RELEASE=1` | Advertises FUTURERELEASE, then drops every hold |
| `MOCK_NO_REGISTRY=1` | Omits the Stalwart capability, so the sign-in refusal can be tested |
| `MOCK_NO_SCHEDULING_SEND=1` | Refuses a calendar write that asks for scheduling messages, as for an account without that permission |
| `MOCK_ROLE` | Who the demo user is for Administration: `admin` (the default), `tenant-admin`, `helpdesk` or `user` |
| `MOCK_METRICS=off` | Refuses the dashboard's metric history, as Community does |
| `MOCK_EDITION=enterprise` | Reports Enterprise, which Tenants needs |
It tracks the current Stalwart release rather than 0.16 in general, and each
behaviour is confirmed against a real server before it is copied here — the
comments say which version and on what date. Where a release changes something
a client can see, the mock changes with it, and the test that pinned the old
behaviour is rewritten rather than deleted, so the reversal stays on the record.
#### Version numbers
`2026.8.30+pr129` is the date of the commit a build came from and the pull
request that commit arrived through; a commit that did not come through one
carries its short SHA instead (`2026.8.30+g1fa6578`). It is worked out from git
at build time — nothing writes a version into the tree, and `package.json` stays
at `0.0.0`. `node scripts/version.mjs` prints it for the current checkout.
The PR number sits after the `+` as build metadata because it records where a
build came from, not how new it is. The version says nothing about Stalwart on
purpose: what a build needs from the server is stated in the README badge and
in [KNOWN-ISSUES.md](KNOWN-ISSUES.md). Building an image with the version on it,
and the single-host `deploy.example.sh`, are covered in
[Installing](https://docs.ihasmail.org/install/).
