Fast local-first Rust CLI for codebase metrics, AST-compressed LLM context bundles, and built-in MCP server.

Sephera is a local-first Rust CLI that combines repository metrics and deterministic context export. It provides fast line counting, deterministic context bundles with AST compression, and a built-in MCP server for AI agent integration. It focuses on giving reliable structural signals and focused context for LLMs and humans.
