Highlights

• Pyodide/Emscripten (wasm32) Python wheel — a reduced-feature wasm32-unknown-emscripten Python wheel now ships, enabling the embedded Python builtin in browser/wasm hosts (#1811).
• Broad resource-safety hardening sweep — fuel/budget enforcement and memory caps across the interpreter, parser, rg, sqlite, snapshot, and expansion paths (arithmetic expansion bounds, coproc/process-substitution budgets, heredoc reinjection fuel, brace-step overflow, compound-array limits, replacement-growth caps, sqlite result memory cap).
• JS BashTool snapshot authentication plus keyed snapshot APIs and snapshot counter/byte-accounting fixes for correct resume.
• Benches snapshot site page and CI hardening for the release/publish workflows.
