v1.5.0-beta.4

Prerelease. First release under the new name @mjayb/sonicweb (formerly @mjayb/sonicpijs). The project is now Sonic Web, live at sonicweb.cc. Bundles all work merged since beta.3. Install: npm install @mjayb/sonicweb.

Rebrand

• Sonic Pi Web → Sonic Web. npm @mjayb/sonicpijs → @mjayb/sonicweb, repo SonicPiWeb → SonicWeb, domain sonicpi.cc → sonicweb.cc (308 redirect, old paths preserved). Upstream Sonic Pi attribution and the audio-critical sonic-pi-* synthdef/OSC identifiers are unchanged. (#610, #611, #614)

Engine

• Self-sufficient by default (#604) — the engine auto-loads SuperSonic (the GPL scsynth WASM core, from CDN), the tree-sitter transpiler, and its PRNG table itself. A bare consumer needs zero runtime wiring.
• Hash#length / #size / #count transpile correctly via a runtime __spSize helper (#603) — fixes loops over Hash literals silently dropping layers.
• spread(hits, total) matches Desktop Sonic Pi's redistribute placement byte-for-byte for all (hits, total) (#597, #598).
• Parity fixes: dynamic / non-literal use_synth, inline-loop RNG continuity, cross-loop get/set time-frame alignment, and bang-only mixer/volume linting (#585, #586, #588–#593, #595, #596).

Docs & tooling

• Parity dashboards and every docs code snippet are now playable (Run/Stop) with an "open in sonicweb.cc" link; dashboards published to Vercel + Cloudflare R2.
• Fixed the "Engine not ready" race when Run is pressed during engine init.
• CI: actions/checkout / actions/setup-node bumped to v6/v7 (#607).
