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).
