Every fn-value is now a `ptr` to a closure pair `{ ptr thunk, ptr env }`,
not a raw fn-pointer. Top-level fns get an auto-generated adapter
`@ail_<m>_<f>_adapter(ptr %_env, params...)` that ignores env and
forwards to the real fn, plus a static closure constant
`@ail_<m>_<f>_clos = { @adapter, null }`. References to a fn as a
value return the closure-pair address.
Indirect calls now GEP the thunk + env slots, load both, and call
`thunk(env, args...)`. Direct calls to statically-known callees stay
on the original fast path (no adapter).
This is the ABI groundwork for Iter 8b lambdas: a captured-env closure
will reuse the same value shape, just with a non-null env produced by
malloc.
Tests: 48 still green. IR snapshots refreshed (every fn now carries an
adapter + static closure pair). Iter 7's hof.ail.json prints 42
unchanged — `apply(inc, 41)` now hands `@ail_hof_inc_clos` to apply,
which unpacks and indirect-calls as designed.
