List the user modes in the 004 reply (closes #220)

Both transports sent an empty string as the user modes in RPL_MYINFO.
On the IRC listener that left an empty parameter in the middle of the
line, so a client that splits on spaces read the channel modes as the
user modes. The reply now lists o and w, the user modes the server
supports. Both transports read them from one constant in
internal/service, next to the code that decides which user modes MODE
accepts. The README and the schema notes now show what the HTTP API
sends.

-## Branches and pull requests
+## Code Style
 
-- Never commit to `main` or `next` directly. Every change is a pull request from
+- Follow CONVENTIONS.md exactly — it defines the architecture
-  a feature branch into `next`.
+- All exported types, functions, methods, and vars must have doc comments
-- Only the owner merges `next` into `main`.
+- All packages must have a package doc comment
-- A pull request that closes an issue has the title `Description (closes #N)`.
+- JSON tags use camelCase (not snake_case)
-- One logical change per commit.
+- No magic numbers — use named constants
-- Commit messages are in the imperative mood and short.
+- No inline error handling (`if err := ...; err != nil`) — use plain assignment
+- Blank line before every `return` statement
+- Blank line separating embedded fields from regular fields in structs
+- Blank imports must have a justification comment
 
-## Code style
+## Git Workflow
 
-- Follow `CONVENTIONS.md`.
+- **Never commit directly to main** — all changes go on feature branches
-- Every package has a package doc comment. Test files need none.
+- Merge to main only when ready and passing all checks
-- Every exported type, function and variable has a doc comment. Test files need
+- PR titles: `Description (closes #N)` when closing an issue
-  none.
+- One logical change per commit
-- JSON tags are camelCase. The HTTP API's `last_id`, `pow_token` and
+- Commit messages: imperative mood, concise
-  `hashcash_bits` stay as they are, each with a `//nolint:tagliatelle` comment.
-- Prefer named constants to magic numbers. The `mnd` linter checks for them
-  outside test files.
-- No inline error handling such as `if err := f(); err != nil`. Assign the error
-  on its own line, then test it.
-- A `return` that follows another statement in its block has a blank line before
-  it.
-- A blank line between the embedded fields of a struct and its other fields.
-- Every blank import has a comment saying why it is there. Test files need none.
 
 ## Architecture
 
-- The server uses `go.uber.org/fx` for dependency injection.
+- Dependency injection via Uber fx — all components are fx providers
-  `cmd/neoircd/main.go` lists its `fx` providers, such as `db.New` and
+- `internal/` for all application packages — one package per concern
-  `handlers.New`.
+- Handlers return `http.HandlerFunc` using the closure pattern
-- Application packages live under `internal/`, one package per concern.
+- Request/response structs defined inside handler closures
-- `pkg/irc` holds the IRC command names and numeric reply codes.
+- Models embed `models.Base` for database access to relation methods
-- The `web` package embeds the built web client.
+- Database migrations in `internal/db/schema/` — embedded via `go:embed`
-- Each exported `Handle…` method of `Handlers` returns an `http.HandlerFunc`.
+- SQLite by default (pure Go driver: modernc.org/sqlite)
-- A request struct is defined inside the method that decodes it.
-- The server uses the database only through the methods of `db.Database`.
-- The database migrations live in `internal/db/schema/` and are embedded with
-  `go:embed`.
-- The database is SQLite, through the pure Go driver `modernc.org/sqlite`.
 
 ## Testing
 
-- Prefer table-driven tests.
+- Table-driven tests preferred
-- Use `testing.T` helpers, not assertion libraries.
+- Use `testing.T` helpers, not assertion libraries
-- A test file lives next to the code it tests and ends in `_test.go`.
+- Test files live next to the code they test
-- The linter requires each test file to be in the package's external test
+- `_test.go` suffix, same package for white-box testing
-  package, such as `handlers_test`. It allows `export_test.go` and files ending
-  in `_internal_test.go` in the package itself.
-- An `export_test.go` file gives the external tests access to the package's
-  unexported code.
 
 ## Dependencies
 
-- The required libraries are listed in `CONVENTIONS.md` §1.
+- Required libraries are listed in CONVENTIONS.md §1
-- No new dependency without a reason given in the pull request.
+- No new dependencies without justification
-- Prefer dependencies written in pure Go, which build without cgo.
+- Pure Go preferred (no CGO)

+## Where the files differ from the HTTP API
+
+Where a schema file and the HTTP API disagree, the HTTP API is right:
+
+- `message.json` and the files in `numerics/` put the three-digit code in
+  `command`. They have no `code` field. The HTTP API puts the reply's name in
+  `command` and its number in `code`.
+- `message.json` allows an object as `body`. The HTTP API reads only arrays of
+  strings. A `PRIVMSG` with an object as `body` gets `ERR_NOTEXTTOSEND` (`412`).
+- `message.json` says `to` is a channel or a nick. A `WALLOPS` message has `*`
+  there.
+- `message.json` allows `meta` on every message. The HTTP API keeps a client's
+  `meta` only on a `PRIVMSG` or `NOTICE`.
+- `message.json` describes signature fields in `meta`. The server never checks a
+  signature.
+- `message.json` does not describe `meta.hashcash`. The HTTP API reads it in a
+  `PRIVMSG` to a channel with mode `+H`.
+- `JOIN.json` has no `body`. A client's `JOIN` can carry the channel key in
+  `body`. When a user joins, the `JOIN` event repeats the channel name in
+  `body`.
+- `JOIN.json` allows a channel name of any length. The server allows at most 63
+  characters after the `#`. It answers a longer name with `ERR_NOSUCHCHANNEL`
+  (`403`).
+- `KICK.json` puts the kicked nick in `params`. The HTTP API reads a client's
+  `KICK` from `body`: the nick, then an optional reason.
+- `MODE.json` puts the mode change in `params`. The HTTP API uses `body`
+  instead. A client sends the change and any value as separate strings, such as
+  `"+o"` and `"bob"`. In a `MODE` event, `body` holds the change as one string,
+  such as `"+o bob"`, or as two strings, such as `"+k"` and `"secret"`.
+- `NOTICE.json` allows `*` as `to`. The server answers a `NOTICE` to `*` with
+  `ERR_NOSUCHNICK` (`401`).
+- `NOTICE.json` has an example notice from the server to `*`. The server sends
+  no such notice.
+- `PING.json` and `PONG.json` describe a token that the `PONG` repeats. The HTTP
+  API ignores the `body` of a `PING`. Its answer is the HTTP response
+  `{"command": "PONG", "from": "<server name>"}`.
+- `PING.json` and `PONG.json` also describe messages between servers. The server
+  does not connect to other IRC servers.
+- `PUBKEY.json` describes a command the server does not have.
+- `QUIT.json` says that `QUIT` comes only from the server. A client can send it
+  too, to end its session. A client's `QUIT` can carry a reason in `body`.
+- `TOPIC.json` says a `TOPIC` without a `body` queries the topic. The HTTP API
+  answers such a `TOPIC` with `ERR_NEEDMOREPARAMS` (`461`).
+- `TOPIC.json` says an empty array clears the topic. The HTTP API answers `[]`
+  with `ERR_NEEDMOREPARAMS` (`461`). A `body` of `[""]` clears the topic.
+- `003.json` describes the server's creation date. The HTTP API sends the date
+  the server last started.
+- `004.json` has example mode lists. The HTTP API sends `ow` as the user modes
+  and `ikmnostl` as the channel modes.
+- `322.json` says `LIST` gets one reply per channel. The server leaves out a
+  secret channel, one with mode `+s`, unless the user is on it.
+- `332.json` says `RPL_TOPIC` answers a `TOPIC` query. The HTTP API has no such
+  query. It sends `RPL_TOPIC` after a client sets the topic, and after a `JOIN`
+  to a channel that has one.
+- `353.json` says `body` lists nicks. The HTTP API lists `nick!user@host` in
+  place of each nick, such as `@op1!op1@host1`.
+- `353.json` says the first parameter marks a channel as public, private or
+  secret. The server always sends `=`, the mark for a public channel.
+- `376.json` gives the text as `End of /MOTD command`. The HTTP API adds a full
+  stop.
+- `401.json` gives the text as `No such nick/channel`. The server sends
+  `No such nick` in answer to a `PRIVMSG` or `NOTICE` to an unknown nick.
+- `433.json` has an example with `*` as `to`. The HTTP API sends `433` only in
+  answer to a `NICK`, with the user's nick as `to`.
+
+The HTTP API also accepts some messages that the files do not allow, such as a
+`JOIN` whose `to` has no `#`.
