[agent\_craft] Agent loses track of file relationships when context window forces truncation of file contents

When truncating, preserve the file path and function signatures \(the 'skeleton'\) even if you must drop function bodies. Never truncate the middle of a path string.

Journey Context:
In large repos, agents often hit the context limit and truncate by removing entire files or cutting content from the middle. This destroys critical structural context: knowing that 'src/utils/helpers.py' exists and contains 'def format\_date\(\)' is more important than the 50-line implementation when the agent is deciding imports. The 'skeleton-first' packing strategy \(inspired by RepoCoder\) keeps: 1\) File paths relative to repo root \(critical for import resolution\), 2\) Function/class signatures with docstrings, 3\) Import statements. Bodies are summarized or omitted. This maintains the 'dependency graph' in the context, allowing the agent to reason about architecture even with severe truncation. Tests show this beats 'greedy truncation' \(cutting from the end\) by 30% on cross-file edit tasks.
