All six produce their target outputs cleanly today; renamed out of
the `issue-*` namespace per CLAUDE.md "Resolving an open issue":
| Old | New |
|----------------------|-------------------------------------------|
| issue-0032 | 181-impl-duplicate-same-file |
| issue-0041 | 182-compound-type-in-expression |
| issue-0042 | 183-type-alias-size-align |
| issue-0044 | 184-objc-defined-class-method-self |
| issue-0045 | 185-pack-fn-comptime-return |
| issue-0046 | 186-nested-comptime-return |
Comment headers tightened to feature-focused (drop the issue-NNNN
provenance — that's in git history now). Missing expected `.txt` /
`.exit` files captured for 0041 + 0042 (they were untracked because
the bugs were fixed silently in adjacent work).
`examples/issue-*` after this commit: just `issue-0030.sx` — a
feature request (`extern G : T;` cross-file globals) that's never
been implemented. Staying in the issue namespace as a parked
proposal until the feature lands or gets formally rejected.
220/220 example tests + `zig build test` green.
