Module context_prefill 

Context prefill assembly for mana dispatch.

When imp run <unit_id> dispatches an agent, the unit description often references files the agent will need. Instead of making the agent spend turns reading those files, we assemble them into a cached prefix message that precedes the task prompt.

The assembled context gets cache_control breakpoints so every subsequent turn in the agent’s session gets cache_read on the file contents — no re-transmission cost.
