v0.59.2

Released 2026-06-29.

Native Messaging — all hosts re-chunk (#389)

• #2814 — all four example hosts now re-chunk their responses to the ≤1 MiB
  browser cap. nm_js2wasm_deno and nm_js2wasm_wasi_p1 were echoing the whole
  message verbatim; they now stream ≤1 MiB JSON frames like
  nm_js2wasm_node_fs/nm_js2wasm_node_process, so no host sends >1 MB in a
  single message (the real Chrome native-messaging host→extension limit). Verified
  byte-exact reassembly at 1 / 64 / 128 / 256 MiB under real wasmtime v46 for all
  four. Two incidental main bugs were fixed along the way: the matrix
  node_process 64/128 MiB cases (red since #2810) and issue-2684's single-file
  compile of the bundled deno example (unsatisfiable env.runNmHost import).

Fixes

• #2815 — suppress the spurious Cannot find name 'Deno' diagnostic for the
  recognized Deno.{stdin,stdout,stderr} surface (the multi-file analyzer wasn't
  injecting the ambient Deno d.ts the single-source path already had).
• #2811 — capture/globalize builtin-named vars + destructuring-param closure
  TDZ-flag offset.

Docs

• #2812 — Native Messaging deployment recipe (wasmtime shebang / bun -b /
  deno compile + manifest).
• #2813 — running --target wasi output across runtimes (wasmtime -W flags
  • the all-proposals caveat, bun -b, deno).
• #2817 — tracked: nm_node_process's env.__wasiStdinStop host import needs
  a WASI-native fallback.
