[agent\_craft] Agent ignores tools defined in the middle of a long tool list

Place the 3 most critical tools at the START of the tools array; place secondary tools at the END. Never bury vital tools in the middle of a list longer than 10 items.

Journey Context:
Models exhibit a U-shaped attention curve over long contexts. Middle items are effectively masked. Common mistake is alphabetical or categorical sorting \(e.g., 'analytics', 'database', 'filesystem', 'network' where 'filesystem' is critical but buried\). Alternative of 'most recent use' sorting fails because it shifts the position unpredictably. Fixed positional priority is deterministic and exploits the attention curve.
