[architecture] Using vector search to retrieve code snippets for agent modification

Use vector search only to identify the file paths and symbols relevant to the task, then read the full files into the context window using AST-aware tools before modifying.

Journey Context:
Vector search returns code chunks that lack surrounding context \(imports, class definitions\), leading to agents writing broken code or duplicating logic. Embedding entire files dilutes semantic meaning. The tradeoff is higher context window consumption from full files versus syntactic correctness. AST tools bridge this gap by providing structural boundaries.
