First iteration of the loop-recur milestone: Term::Loop /
Term::Recur / LoopBinder as strictly-additive nodes across all six
crates' no-wildcard Term matches, parse/print/round-trip,
hash-stability + drift anchors. No typecheck semantics (synth
stubs CheckError::Internal — iter 2), no real codegen (lower_term
stubs CodegenError::Internal — iter 3); both stub points mirror
mut.1. Two Boss calls baked into the plan header: (1)
verify_tail_positions 'byte-unchanged' = tail-app role unchanged,
operationalised via the tail-app IR-snapshot non-regression test
(literal source freeze impossible — exhaustive no-wildcard match);
(2) codegen is in iter-1 scope as stubs/pass-throughs because the
workspace must compile for cargo test --workspace (the iter goal).
Recon DONE_WITH_CONCERNS — all three open questions resolved at
plan time (Q3: print.rs:352 is a Type match, untouched).
