Closes #163

The Clojure server page, libtmux.core/open!, shows no "What is on here" table, where Julia's LibTmux.Server and Rust's Server do. This adds the directory to the open! docstring. The table appears on that page once this merges and libtmux/docs reads the [[name]] spelling (libtmux/docs#318).

Owner symbol. libtmux.core/open!, not the libtmux.core namespace. The docs concept map binds the server concept to libtmux.core/open!, so that is the page other ports link as Clojure's server and the page the issue reports. The namespace docstring is two sentences on the module page, which already lists its vars.

What is on it. Nine rows, each a bold lead, guidance, and a Label: [[ref]], [[ref]] list: connecting and closing, listing everything, finding one thing, creating and removing, acting on objects, typing into panes and reading them, options and hooks and environment, buffers and channels, running a command. Every public libtmux.core var is listed once, with the libtmux.data vars a caller uses to traverse and filter a capture, and libtmux.control/attach!.

Reference spelling. [[name]] for a libtmux.core var and [[libtmux.data/name]] for another namespace, the cljdoc wiki link WRITING.md prescribes and the native reference already resolves. It rejects an unknown target, so a renamed var fails check. libtmux/docs needs a Clojure entry in BY_PORT in api-directory.ts, /\[\[[^\]\n]+\]\]/; until then the shell reads Clojure with the shared patterns and draws no table.

Changelog. None: the Clojure module has not shipped, and the unreleased Documented entry already covers its API references.

Verification

Run on this branch (wall time includes the heavy.sh slot wait):

Command	Result
./gradlew :libtmux-clojure:check	pass, 39 s: 61 tests, 371 assertions, plus checkClojureApiReference
./gradlew :libtmux-clojure:updateClojureApiReference then check	docs/guide/clojure-api.md regenerated and fresh
exportClojureApi from libtmux/docs at this head, then extractClojure and groupDirectory with the [[name]] pattern added	90 declarations exported; the open! body folds into 9 rows with 62 distinct references; without the pattern, 0 rows

The new test, server-directory-names-every-core-function in libtmux.internal.package-test, was shown to fail:

• On the base docstring (no directory): 0 rows, and every public libtmux.core var reported missing.
• With split-pane! dropped from the Create list, through ./gradlew :libtmux-clojure:clojureTest: #{"libtmux.core/split-pane!"} reported missing.
• With the word then among the references of the Remove list: the prose assertion failed. (and is allowed, as the site allows it.)

First row as exported by the docs model:

{
  "title": "Connecting and closing",
  "guidance": "[[open!]] returns a Server for one explicit `:socket-path` or `:socket-name`, which `with-open` closes. [[close!]] releases only that client and never kills tmux. [[libtmux.control/attach!]] attaches a separate control connection to a captured session.",
  "groups": [
    { "label": "Open and close", "refs": ["[[open!]]", "[[close!]]"] },
    { "label": "Control", "refs": ["[[libtmux.control/attach!]]"] }
  ]
