Clojure support

[p14n]

🤔 What's changed?

Added support for the Clojure language.

⚡️ What's your motivation?

Currently, the Cucumber plugin in Vscode does not recognise step definitions written in clojure. This is the first step.

• Add Clojure language support (src/language/clojureLanguage.ts)

  • Step definition detection via tree-sitter queries (Given, When, Then, And, But)
  • Handles both cucumber expressions ("I am user {string}") and regex patterns (#"^a regexp$")
  • Strings containing regex capture groups are automatically treated as regular expressions
  • Snippet generation for step definitions

• Add 'clojure' to LanguageNames in src/language/types.ts

• Register Clojure in src/language/languages.ts

• Add @yogthos/tree-sitter-clojure as optional dependency for parsing

• Add Clojure parser loading in src/tree-sitter-node/clojureParser.ts

• Add Clojure to NodeParserAdapter and wasm build script

• Add test data (test/language/testdata/clojure/StepDefinitions.clj)

• Update README.md to list Clojure as a supported language

Companion PRs needed:

• cucumber/language-server — add .clj/.cljc/.cljs to glue file extensions
• cucumber/vscode — add clojure to document selector and default glue patterns

🏷️ What kind of change is this?

• ⚡ New feature (non-breaking change which adds new behaviour)
