Keep neoirc-cli responding when a key or a typed line updates the screen (closes #223 )

The Enter handler of the input line and the Alt and digit key handler ran the typed line on the tview event loop. Every UI method that changes the screen waits for that loop, so the client stopped responding. Each line now runs on its own goroutine, which first waits for the line before it, so lines keep the order they were typed in. /window now runs off the event loop. It reads the buffer name through the new BufferName, which runs on the loop, and switches only when that buffer exists. One new test drives a running UI on a simulation screen with Alt and 1, then a typed line and Enter. Another holds the first line and checks that the second waits for it. Model: opus-5-5

-## 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)

- `MODE.json`: querying or changing a channel's modes or the user's own modes.
+- `MODE.json`: a channel mode was changed.
- `KICK.json`: a channel operator removing a user from a channel.

- `001.json`: `RPL_WELCOME`, which welcomes the user.
+- `001.json`: `RPL_WELCOME`, which welcomes a new user.

 ## 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 an empty string 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 `#`.
