[agent\_craft] Agent exceeding context window or losing track of definitions when including entire file contents

Use 'signature-only' context packing: include full content only for the focal file, and for dependencies include only function signatures, type definitions, and docstrings extracted via AST, not full implementations

Journey Context:
Coding agents often retrieve context by including entire file contents of related modules. This is token-inefficient and triggers 'lost in the middle' issues where critical definitions are buried in irrelevant implementation details. Humans don't read full files when navigating; they jump to definitions. Agents should mimic this via hierarchical context packing: the file being edited gets full text; imported/related files get 'skeleton' views \(AST-extracted signatures\). This reduces token count by 80-90% while preserving semantic relevance. Implementation requires AST parsing \(tree-sitter\) to generate outlines dynamically, or pre-indexed 'skeleton' files.
