feat: rust extractor code

[AbianS]

• Implement extractRustEntities() for parsing Rust AST via tree-sitter
• Extract structs, enums, traits, impls, functions, methods, modules, macros, and imports
• Support generic types, visibility modifiers, async/const/unsafe function flags
• Track line numbers and parse doc comments (/// and /** */)
• Qualified names for methods (e.g., Calculator::add)
• Add 12 test suites with 30+ test cases covering all entity types
• Include unit tests for generics, docstrings, visibility, and line number tracking
• Add CLI commands for commit, create-github-issue, and fix-github-issue

Summary by CodeRabbit

• New Features

  • Added Rust support: parsing, symbol extraction, and analysis across the codebase.

• Documentation

  • Added procedural guides for creating conventional commits and for creating/fixing GitHub issues via CLI.

• Tests

  • Added extensive tests covering Rust parsing and extraction behavior.

• Chores

  • Updated development dependencies and added a changeset noting the Rust extractor feature.

Walkthrough

Adds Rust language support via a new tree-sitter-based Rust extractor and parser updates; adds comprehensive Rust extractor tests; introduces three Claude command docs for commit and GitHub issue workflows; and updates several dependencies and meta files.

Changes

Cohort / File(s)	Summary
Rust Extractor & Types apps/server/src/code/extractors/rust.ts, apps/server/src/code/types.ts	New Rust extractor extractRustEntities added; EntityType and AnalysisResult unions extended with Rust kinds (struct, enum, trait, impl, mod, macro) and language = rust.
Parser & Integration apps/server/src/code/parser.ts, apps/server/src/code/index.ts	Parser updated to load and parse Rust grammar (rust accepted in loadLanguage/parseCode/detectLanguage); index routes Rust trees to the Rust extractor and updates entity type ordering.
Rust Tests apps/server/tests/code/parser.test.ts, apps/server/tests/code/rust.test.ts	Adds parser tests for Rust detection/loading and comprehensive extractor tests validating structs, enums, traits, impls, functions/methods, modules, macros, imports, docstrings, and line numbers.
Claude Command Docs .claude/commands/commit.md, .claude/commands/create-github-issue.md, .claude/commands/fix-github-issue.md	New documentation files describing AI-assisted commit creation (Conventional Commits), GitHub issue creation via gh CLI, and guided issue-fix workflow.
Dependency & Config Updates apps/server/package.json, apps/tui/package.json, package.json, biome.json, .changeset/breezy-aliens-cry.md	Dependency bumps and additions: @modelcontextprotocol/sdk 1.25.2→1.25.3, added tree-sitter-rust@0.24.0, @types/bun bumped, @biomejs/biome & turbo bumped; biome schema version updated; new changeset added.
