apl: right-to-left parser + 44 tests (Phase 1, step 2)
Test, Build, and Deploy / test-build-deploy (push) Failing after 17s
Implement lib/apl/parser.sx — APL expression parser:
- Segment-based algorithm: scan L→R collecting {fn,val} segments
- build-tree constructs AST with leftmost-fn = root (right-to-left semantics)
- Handles: monadic/dyadic fns, strands (:vec), assignment (:assign)
- Operators: derived-fn (:derived-fn op fn), inner product (:derived-fn2)
- Outer product ∘.f (:outer), dfns {:dfn stmt...}, guards (:guard cond expr)
- split-statements is bracket-aware (depth tracking prevents splitting inside {})
44 new parser tests + 46 existing tokenizer = 90/90 green.
