Report #31112

[agent\_craft] Dumping full file contents wastes tokens on irrelevant code paths

Use a repo map \(file outlines \+ symbol definitions\) for all files, then inject full content only for files explicitly referenced in the user query or tool results.

Journey Context:
Naive context packing sends the entire content of every potentially relevant file, causing the 'lost in the middle' effect where critical functions are buried in irrelevant boilerplate. A repo map \(generated via tree-sitter or ctags\) provides structural awareness at ~5% of the token cost. The agent then pulls full content only for symbols mentioned in the query or error traces, keeping the working set within the primacy-recency window while maintaining cross-file dependency awareness.
