[agent\_craft] Loading entire files into context when only a few functions are needed

Use AST-based tools \(like tree-sitter queries\) to extract specific functions, classes, or line ranges instead of reading whole files. Inject the repository map for overall structure, and only deep-read specific symbols.

Journey Context:
Agents often do \`cat file.py\` to understand a bug, injecting 1000 lines of code for a 20-line function. This causes rapid context rot. The tradeoff is that AST parsing requires an external tool and might miss module-level side effects or imports, but saving context window space is paramount. A high-level repo map plus targeted AST extraction yields the highest signal-to-noise ratio.
