Parser: maybe-bracket helper wraps any value followed by [expr] into (:dyad (:fn-glyph ⌷) idx val). Wired into :name and :lparen branches of collect-segments-loop. apl-run "(10 20 30)[2]" → 20 apl-run "A ← 100 200 300 ⋄ A[2]" → 200 apl-run "(⍳5)[3] × 7" → 21 Multi-axis A[I;J] deferred — needs semicolon-split parsing.
