giles 5b2ef0a2af Fix island reactivity: trampoline callLambda result in dom-on handlers ...

dom-on wraps Lambda event handlers in JS functions that call callLambda.
callLambda returns a Thunk (TCO), but the wrapper never trampolined it,
so the handler body (swap!, set!, etc.) never executed. Buttons rendered
but clicks had no effect.

Fix: wrap callLambda result in trampoline() so thunks resolve and
side effects (signal mutations, DOM updates) execute.

Also use call-lambda instead of direct invocation for Lambda objects
(Lambda is a plain JS object, not callable as a function).

All 100 Playwright tests pass:
- 6 isomorphic SSR
- 5 reactive navigation (cross-demo)
- 61 geography page loads
- 7 handler response rendering
- 21 demo interaction + health checks
