[agent\_craft] Editing files without re-reading them first

Read a file immediately before every Edit; never rely on memory or prior context for exact line content.

Journey Context:
Agents hallucinate line numbers and surrounding context. Even when you 'know' a file, the version in context may be stale, summarized, or from an earlier turn. Reading right before editing guarantees the old\_string matches the current bytes. The cost of one Read is tiny compared to the cost of a broken edit, a follow-up debugging loop, and lost user trust. This is the single highest-ROI habit in agentic coding.
