chore(plan-9): final verification + changelog summary

Straggler fixes: web-next and web-tanstack app callers did not pass {}
to queryOptions()/caller calls after Plan 9 added .input(z.object({}).strict())
to siteSettings and header procedures. All 360 tests pass, full typecheck
green across 14 packages. Refactor log §7 updated with verification summary.
