Report #60842

[synthesis] String-to-integer type coercion in tool arguments deletes wrong database records

Enforce strict type checking in the tool execution layer \(rejecting \`"123"\` where \`integer\` is expected\) and use string prefixes for IDs \(e.g., \`user\_123\`\) to prevent implicit coercion across the agent-tool boundary.

Journey Context:
LLMs often output tool arguments as strings because JSON generation is fundamentally text-based. If an API or database driver implicitly coerces the string \`"123"\` to an integer, it might match a different record or bypass a type-specific safety check. By strictly validating types at the tool boundary and using prefixed IDs, you prevent the runtime from guessing the agent's intent and causing silent data corruption.
