Tool changes

No tool definition changes recorded. A server's first observation is its baseline; later probes record what changes.

Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed. How it is computed.

`check_expense`read-only	Say whether a college expense is a qualified 529 expense (for example 'laptop', 'off-campus rent', 'gas', 'student health insurance') with the reason, based on IRS Publication 970.
`compare_529_plans`read-only	Compare two to four 529 plans side by side on fees, ratings, tax benefit, minimums and who can join.
`estimate_college_cost`read-only	Project what college will cost and what to save. Give a US school id and the year the student starts. Returns the projected cost per year and in total, and the monthly amount that would fully fund it from today, assuming steady returns after the plan's fees.

`get_school`read-only	Details for one US school by id: current sticker price, average net price, net price by family income, cost history since 2005, graduation rate and median earnings. Get the id from search_schools.
`list_529_plans`read-only	List state 529 savings plans, ranked by popularity and ratings, with fees, Morningstar and Saving For College ratings, state tax benefit and whether residents of other states can join. Filter by state, by plans anyone can open, by maximum yearly fee, or by minimum rating.
`search_schools`read-only	Find colleges and universities by name, in the US and 529-eligible schools abroad. Returns each school's id, location and annual published costs (tuition, room and board, books). Use get_school with the id for cost history and net price.
