Fix &rest param binding in OCaml evaluator + clean test suite: 0 failures

Browse Source 
OCaml evaluator: has_rest_param and bind_lambda_params checked for
String "&rest" but the parser produces Symbol "&rest". Both forms now
accepted. Fixes swap! extra args (signal 10 → swap! s + 5 → 15).

test-adapter-html.sx: fix define shorthand → explicit fn form, move
defcomp/defisland to top level with (test-env) for component resolution.

2515 passed, 0 failed.
