feat: step sequencer demo — reactive pads, playhead, BPM
Step sequencer: 4 instruments × 8 steps, timer-driven playhead,
toggleable pads, BPM controls with streaming. 75 lines of .ds code.
Parser fixes:
- UI elements checked before LParen (button (if ...) is element, not call)
- Element args support parenthesized expressions: button (if cond ...)
- StringInterp recognized as valid string start in parse_primary/parse_element
Codegen fixes:
- emit_expr checks local_vars: loop var i emits 'i' not 'i.value'
- Array index mutations re-trigger signal: pads.value = [...pads.value]
