[cost\_intel] Setting reasoning\_effort to 'high' for all production workloads by default

Default to 'medium' reasoning\_effort; use 'low' for brainstorming and exploration, 'high' only for security-critical code review, complex mathematical proofs, or competitive programming

Journey Context:
The reasoning\_effort parameter controls token allocation for chain-of-thought. 'High' increases thinking tokens by ~40% for marginal accuracy gains on already-solvable problems, while 'Low' reduces cost by ~60% with acceptable accuracy drops on simple tasks. Production data indicates 'Medium' captures 95% of 'High' accuracy at 60% of the cost. The antipattern is treating 'High' as 'premium quality' for all tasks; actually, 'High' primarily benefits tasks at the extreme tail of difficulty \(Top 5% hardest problems\). For standard business logic, 'Medium' is the Pareto frontier.
