test: banner purge + WHY-only comment sweep (rule 8)

Browse Source 
Every section banner dies (103 -> 0) across test/lang, the observer
suites, the C carriers, and the five comment-heavy corpus fixtures;
banner provenance (#N cites, carrier numbers, repair-cluster labels)
folded into headers or adjacent WHY comments. Narration deleted; row
provenance, ref cites, divergence pins, and layout contracts kept
(fwd-ref decl-order guards and bootstrap-gate corpus rationale
restored where the sweep over-cut). Comment-only proven: all 3742
wwbuild workdir .s byte-identical before/after; test-commit and
test-byteid (161 lang + 1399 data, 0 pinned-divergent) green.

* 993_ww_ww — explicit bootstrap gate for the ww-side driver port.
*
* Diffs the C-built `ww` against the ww-built `ww_ww`. Both drivers
* Explicit bootstrap gate: the C-built `ww` and the ww-built `ww_ww`
* orchestrate the same w6c/w6a/w6l, so the resulting binaries must be
* byte-identical for every program in the corpus. The corpus mixes:
* - a tiny single-file program (no -I flags)
* - a multi-import build (selfhost/cmd/wwdump/main.ww), exercising
* `use` resolution + the -I search path + the libwwrt.a link.
*
* Each build runs from a per-driver scratch directory so the
* intermediate .s/.o files don't collide.
