TZPL v0.1.0

First public release of TZPL, an audio coding platform combining:

• Tzopilotl -- a statically typed, real-time safe interpreted language with a direct-threaded VM, TLSF allocator, and incremental GC
• synthdef-compiler -- compiles audio signal-flow graphs into optimized native plugins via a 14-pass analysis pipeline
• engine -- a real-time audio engine with dynamic graph patching, lock-free threading, multi-silo parallelism, crossfading, and sample-accurate scheduling
• app -- a JUCE-based GUI with a multi-tab editor, REPL, notebooks, and live controls

Highlights leading up to this release

Language & VM

• panic builtin, and error halts that actually halt -- defSynth/defSynthX fail loud instead of continuing on a broken graph
• Int / Int fuses into a single DIV_INT_TO_FRAC opcode
• User-defined indexing: obj[idx] rewrites to at(obj, idx), with the full at/put! subscript protocol; ranges are indexable

SynthDefs & UGens

• Integer bit operations end-to-end in synthdefs, with indexed delay state and an in-place put peephole optimization
• The pink-noise family (pink, blue, violet, red, gray, white) with corrected Kellett filter state reads
• Voicer fixes: non-power-of-two voice counts, per-voice shape through PhiNode, compiler parity on instruments.x
• fadeout ugen, rpanfun, and d(0) resolving to the written signal

Engine & Control

• setControl by control name across the engine, OSC, and NATS interfaces
• NRT renders honor setTempo

Libraries & Examples

• instruments.x: a note-playing instrument synthdef library (Karplus-Strong pluck, wavetable lead, resonator bank, sample players)
• examples/music_fx_demos.x: three multi-section demos tying the music dialects, instruments, and effects libraries together

Docs & Site

• Documentation site with landing page, ⌘K search, per-chapter guide pages, and an audio gallery
