Report #8578

[agent\_craft] Full repository tree consumes 30% of context window with irrelevant paths

Use a 'reverse repository map': list files starting from the target file's directory upward, truncating deep trees with '...', and prioritizing files with recent git changes over alphabetical full tree.

Journey Context:
Standard tree views \(root down\) place the target file at the end \(low attention\) and include deep node\_modules. Reverse tree places the target's siblings and parents first \(high attention\). Truncation and git-prioritization leverage temporal locality. This maintains navigability with 80% fewer tokens than full tree.
