apl: end-to-end pipeline apl-run + 25 source-string tests (400/400)

apl-run = parse-apl + apl-eval-ast against empty env.  Wires
tokenizer + parser + transpile + runtime as one entry point.
test.sh now loads tokenizer.sx + parser.sx alongside transpile.sx.

Source-string tests cover scalars, strands, dyadic arith,
right-to-left precedence, monadic primitives, /, \, ⌈/, ×/,
∘.×, +.×, ⍴, comparisons, classic one-liners.

Tokenizer doesn't yet handle decimal literals (3.7 → 3 . 7),
so two such tests substituted with integer min/max-reduce.
