[synthesis] How to provide relevant codebase context to LLMs without exceeding token limits

Implement a hybrid retrieval system \(vector embeddings \+ precise keyword search like ripgrep\) to fetch only the most relevant code snippets into the LLM context, rather than dumping entire files.

Journey Context:
LLMs cannot hold a large codebase in context. Synthesizing Cursor's 'Codebase Indexing' feature with Aider's repository map \(ctags\) reveals that simple vector search is insufficient. The architectural consensus is a hybrid retrieval system: offline embeddings for semantic search combined with real-time ripgrep/ctags for precise symbol lookup. The agent must first search, then read, mimicking human navigation.
