Start test servers on a port the system picks (closes #211)

The internal/server and internal/ircserver tests picked a port by
opening a listener, reading its port and closing it. They then started
a server on that number. Another process could take the port in
between, and a test failed with "address already in use".

The IRC server tests now start the server on 127.0.0.1:0 and read the
port back from its listener. The HTTP server tests start the app with
port 0. The HTTP server now keeps the listener it binds, so the stop
test sends its long poll to the port the app was given.

-# Message schemas
+# Message Schemas
 
-This directory holds JSON Schema files (draft 2020-12) for the messages that the
-neoirc HTTP API carries. `message.json` describes the fields that every message
-can have. `commands/` has files for some commands. `numerics/` has files for
-some of the numeric replies. A numeric reply is a server reply named by a
-three-digit number, such as `001`. `README.md` at the repository root documents
-the protocol.
+JSON Schema definitions (draft 2020-12) for the neoirc protocol. Messages use
+**IRC command names and numeric reply codes** (RFC 1459/2812) encoded as JSON
+over HTTP.
 
-The server can also run an IRC listener for ordinary IRC clients. The IRC
-listener sends plain IRC lines, which these files do not describe.
+## Envelope
 
-## Message fields
-
-Every message is one JSON object, which `message.json` calls the envelope. These
-are the fields it can have:
-
-- `command`: the IRC command name, such as `PRIVMSG`, or the name of a numeric
-  reply, such as `RPL_WELCOME`. Always present.
-- `code`: the number of a numeric reply, such as `1` for `RPL_WELCOME`. Absent
-  on other messages.
-- `id`: the message's UUID, a unique ID that the server assigns.
-- `from`: the sender's nick, or the server name on a numeric reply or a `PONG`.
-- `to`: the target, such as a channel name starting with `#` or a nick.
-- `params`: an array of strings with the message's other parameters, in order.
-  `KICK` events and many numeric replies have it. The HTTP API ignores `params`
-  sent by a client.
-- `body`: an array of strings. It is never a bare string. In a `PRIVMSG` or
-  `NOTICE`, each string is one line of text.
-- `ts`: the time the server stored the message. It is an RFC 3339 time in UTC,
-  such as `2026-10-27T12:00:00.123Z`.
-- `meta`: an object of extra data, such as a hashcash stamp in `meta.hashcash`.
-  A hashcash stamp is a short string that takes a computer some work to make. A
-  `PRIVMSG` to a channel with mode `+H` needs one. The HTTP API relays the
-  `meta` of a `PRIVMSG` or `NOTICE` unchanged. It drops the `meta` of every
-  other command.
-
-Here is one `PRIVMSG` as the IRC listener sends it and as the HTTP API sends it.
-The JSON leaves out `id`, `ts` and `meta`:
+Every message is a JSON object with a `command` field. The format maps directly
+to IRC wire format:
 
 ```
-IRC:  :alice!alice@* PRIVMSG #general :hello world
-JSON: {"command": "PRIVMSG", "from": "alice", "to": "#general", "body": ["hello world"]}
+IRC:  :nick PRIVMSG #channel :hello world
+JSON: {"command": "PRIVMSG", "from": "nick", "to": "#channel", "body": ["hello world"]}
+
+IRC:  :server 353 nick = #channel :user1 @op1 +voice1
+JSON: {"command": "353", "to": "nick", "params": ["=", "#channel"], "body": ["user1 @op1 +voice1"]}
+
+Multiline:  {"command": "PRIVMSG", "to": "#ch", "body": ["line 1", "line 2"]}
+Structured: {"command": "PUBKEY", "body": {"alg": "ed25519", "key": "base64..."}}
 ```
 
-In the JSON, a numeric reply has its name in `command` and its number in `code`.
-This `353` reply lists the members of `#general`. The JSON again leaves out
-`id`, `ts` and `meta`:
+Common fields (see `message.json` for full schema):
 
-```
-{"command": "RPL_NAMREPLY", "code": 353, "from": "neoirc", "to": "alice",
- "params": ["=", "#general"], "body": ["@op1!op1@host1 alice!alice@host2"]}
-```
+| Field     | Type            | Description                                          |
+| --------- | --------------- | ---------------------------------------------------- |
+| `id`      | string (uuid)   | Server-assigned message UUID                         |
+| `command` | string          | IRC command or 3-digit numeric code                  |
+| `from`    | string          | Source nick or server name (IRC prefix)              |
+| `to`      | string          | Target: #channel or nick                             |
+| `params`  | string[]        | Middle parameters (mainly for numerics)              |
+| `body`    | array \| object | Structured body — never a raw string (see below)     |
+| `ts`      | string          | ISO 8601 timestamp (server-assigned, not in raw IRC) |
+| `meta`    | object          | Extensible metadata (signatures, hashes, etc.)       |
 
-A `PRIVMSG` whose `body` has two strings is a two-line message:
+**Structured bodies:** `body` is always an array of strings (for text) or an
+object (for structured data like PUBKEY). Never a raw string. This enables:
 
-```
-{"command": "PRIVMSG", "to": "#general", "body": ["line one", "line two"]}
-```
+- Multiline messages without escape sequences
+- Deterministic canonicalization via RFC 8785 JCS for signing
+- Structured data where needed
 
-## Files
+## Commands
 
-Most command files describe both the message a client sends and the message the
-server sends. Their field descriptions say where the two differ. The examples in
-the files leave out `id`, `ts` and `meta`.
+IRC commands used for client↔server and server↔server communication.

+## Federation (S2S)
+
+Server-to-server messages use the same command format. Federated servers relay
+messages with an additional `origin` field in `meta` to track the source server.
+The PING/PONG commands serve as inter-server keepalives. State sync after link
+establishment uses a burst of JOIN, NICK, TOPIC, and MODE commands.
