All four hints declared on every tool

25/25 tools missing one or more hints — apply_formula (missing: readOnlyHint, idempotentHint, openWorldHint); validate_formula_syntax (missing: destructiveHint, idempotentHint, openWorldHint); format_range (missing: readOnlyHint, idempotentHint, openWorldHint), +22 more. OpenAI's directory rejects tools where any of the four hints are missing or non-boolean.

For every tool, set all four hints (readOnlyHint, destructiveHint, idempotentHint, openWorldHint) to explicit true/false values that match the handler’s actual behaviour.
