Drops the direct-call-only restriction on the LetRec name when it
appears in `in_term`. No new ABI: the lift wraps the in-term in
`(let f (lam P (app f$lr_N P CAPTURES)) in_term')` so codegen's
existing Iter-8b closure-pair machinery handles it. Body-position
name-as-value still rejected (deferred — eta-of-self is harder).
- desugar.rs / lift.rs: split find_non_callee_use into body
(panic) and in_term (wrap).
- examples/local_rec_as_value.{ailx,ail.json}: no-capture path
(factorial passed to apply5 → 120).
- examples/local_rec_as_value_capture.{ailx,ail.json}: capture
path; lifted fn has captures, eta-Lam picks them up via 8b.
- e2e + desugar tests: 113 → 116 (+3).
Codegen Lam machinery handled the wrapped form on the first try.
