giles 59adee0d2b W14: C9 eliminate empty suite labels (test-only) — section E complete
The finding ("spec suites print with empty suite label") was six files
wide: test-chars (43 suite-less top-level deftests), test-import-bind
(14), test-ports (12), test-let-match (8), test-math (deftests NESTED in
deftests — every test reported as " > sin"), and 4 stray deftests between
suites in test-hyperscript-conformance.

Fixes: file-level defsuite wraps for the four flat files (mechanical wrap,
sx_validate-checked); test-math restructured deftest->defsuite ("math >
string->number"); hs strays wrapped in suites named for their section
comments (hs-compat-blockLiteral/cookies/some/where). The two
baseline-visible identities are renamed in spec/tests/known-failures.txt
in this same commit — the F10 gate enforces exactly this coupling.

Full baseline gate validated GREEN: 5798p/273f, fail set identical
(the -2 passes are the two wrapper deftests that no longer self-report
a vacuous PASS around their children).

Test-only: no semantics edits, no push.

;; Math completeness tests. C9 note: this file used NESTED deftests with no

;; Restructured to defsuite/deftest — labels are now "math > sin" etc.
