Add java.classpath missing dependency

[carloshernandez2]

Fix: Add missing org.clojure/java.classpath dependency

Problem

When using metrepl as an nREPL middleware in projects without org.clojure/java.classpath on the classpath, the REPL fails to start with:

Error loading metrepl.middleware.op-metrics: Syntax error macroexpanding at (metrepl/metrics.clj:1:1).
Error loading metrepl.middleware.tests-metrics: Syntax error macroexpanding at (metrepl/metrics.clj:1:1).

When attempting to require metrepl manually:

(require 'metrepl)
;; Execution error (FileNotFoundException) at metrepl.metrics/eval5380$loading (metrics.clj:1).
;; Could not locate clojure/java/classpath__init.class, clojure/java/classpath.clj or clojure/java/classpath.cljc on classpath.

Root Cause

metrepl.metrics namespace requires clojure.java.classpath:

(ns metrepl.metrics
  (:require
   [clojure.java.classpath :as classpath]  ; <-- this dependency is not declared
   ...))

However, org.clojure/java.classpath is not declared as a dependency in deps.edn. This works in many projects because they transitively pull in java.classpath through other dependencies, but fails in minimal projects (like new Leiningen projects with only org.clojure/clojure as a dependency).

Solution

Add org.clojure/java.classpath as an explicit dependency in deps.edn.

Testing

Verified the fix resolves the issue in a minimal Leiningen project that previously failed to start the REPL with metrepl middleware enabled.
