feat(lang): Add Clojure language support

[BuddhiLW]

Summary

Add comprehensive Clojure language support using tree-sitter-clojure-orchard.

Changes

New Parser Module: src/parsing/clojure/

• mod.rs - Module exports
• definition.rs - ClojureDefinition implementation
• parser.rs - AST parsing & symbol extraction (30KB)
• behavior.rs - Runtime behavior tracking
• resolution.rs - Cross-reference resolution
• audit.rs - Code health analysis

Integration:

• Updated Cargo.toml with tree-sitter-clojure-orchard = "0.2.5"
• Registered Clojure in factory.rs, language.rs, registry.rs
• Added .clj, .cljs, .cljc, .edn extensions

Features

• Extracts: defn, defmacro, def, defmulti, defmethod, defprotocol, defrecord, ns
• Handles namespaced symbols and qualified references
• Tracks function calls and dependencies
• Supports docstrings and metadata extraction
• Pattern-based form detection (tree-sitter-clojure is syntax-only)

Testing

Tested with hive-mcp codebase:

• 13,324 symbols indexed successfully
• 4,812 semantic embeddings generated
• All symbol searches working correctly

Documentation

Added contributing/parsers/clojure/IMPLEMENTATION_GUIDE.md (1400 lines) with:

• Architecture overview
• Implementation patterns
• Test cases
• Known limitations

Notes

The Clojure tree-sitter grammar is syntax-only (no semantic nodes for defn etc.), so the parser uses pattern matching on list forms to identify definitions. This approach is documented in the implementation guide.

Hi @BuddhiLW Thank you for your contribution!

A significant update was merged that includes API changes likely to cause conflicts with your branch.

What's changed:

• Unified Envelope format for all --json output (breaking change)
• Cleaned up dead resolution code - resolve_import, build_resolution_context, resolve_import_path and related methods are gone
• file_extensions() no longer exists on LanguageBehavior - switch to LanguageDefinition::extensions()
• Language behaviors now require format_path_as_module trait method
• New src/parsing/paths.rs module with shared path helpers

Please rebase on main. Happy to assist if you encounter any issues.

Hi!

I will be happy to conciliate with updates. Thank you for considering the PR.

One idea I had, because tree-sitter is limited for lisps, I may write a rust module wrapper to use clj-kondo.

I have some thoughts. Because, it will help greatly with token-efficiency in my other project (hive-mcp); and behavior normalization. When I have 5+ claudes and 3+ free models per claude doing work, like refactoring etc.

Sometimes free models will have way less context and hallucinate on function annotations ("types" for clojure) - I noticed.

So, yeah. Let's see... Nice talking to you, anyway.
