[agent\_craft] Parallel tool execution causes race conditions in stateful file operations

Disable parallel tool calls \(set \`parallel\_tool\_calls: false\` or equivalent\) when tools modify shared state \(file writes, database updates\); force sequential execution and require explicit 'read-then-write' confirmation prompts for destructive operations to prevent collision.

Journey Context:
Enabling parallel tool calls for efficiency causes race conditions when two tools try to write to the same file or update the same database row simultaneously, leading to partial writes or lost updates. The agent loses determinism and may corrupt state. Sequential execution is slower but safe for stateful operations. For destructive operations \(delete, overwrite\), requiring an explicit confirmation prompt with the diff preview prevents catastrophic errors from hallucinated parallel tool calls.
