youknowdot 9710aa5162 Test native IR invariants and harden append-fold helper contract (#9370) ...

Retain direct IR coverage for constant-pool representations, malformed
append-sequence rejection, and vacated instruction-slot metadata reuse.
Reject non-unit terminal append depths at the private folding helper.
Existing production callers already require depth one; this is defensive
contract hardening, not a newly fixed reachable interpreter bug.

Preserve the existing helper structure and all pre-existing tests. The
three added native tests are unchanged from the Python 3.15 upgrade work.

Validation: codegen check and strict Clippy with --tests, a --lib --no-run
build, and exactly three bounded native IR tests (one pass, zero ignored
each). No Python, parser, VM or lifecycle payload was executed. The
symmetric SetAdd guard has no dedicated depth-two assertion.
