'ww test' gains the istest build path (-T injection in build_one/
buildone) and do_test/dotest accept -I, mirroring do_run - both twins.
The 35 converted lib tests drop their interim bare mains (-T
synthesizes the entry from @test fns and rejects a user main); their
35 C run-drivers flip 'ww run' -> 'ww test'; 989_lib_byteid compiles
lib tests under -T (8 user-main probe fixtures stay non-T, gated on
the fixture field). Abort-on-first-failure stands until the deferred
record-and-continue harness lands with the multi-package arc.
Fold the ~88-arm `if (k == tkind.TK_X) return "..."` ladder in tokname
to a single `switch (k)` with the terminal `return "<?>"` as the
fall-past default. kwlookup stays an if-ladder: it dispatches on
streqn() string compares over distinct literals, which a value-switch
can't express.
Not byte-id-neutral (if-chain -> switch dispatch changes the asm), so
the ladder->switch equivalence is pinned by a new table-driven test:
lib/ww/lex/toktest.ww drives tokname over every tkind plus the
out-of-band "<?>" fallback, and kwlookup over every keyword plus
non-keywords, wired as 904_tok_run (same `ww run` @test shape as
904_ascii_run). The 990_selfhost wwdump diff only covers kinds that
appear in its corpus.
Regenerates the w6c + wwdump combined.ww amalgamations (tokname region
only).
