Upgrade CI, release builds, and @types/node to Node 26 LTS. Node 26 entered Active LTS on 2026-10-28; 26.13.0 includes the October 2026 security fix from 26.12.1. Exact version pinned so the runner tool cache can't serve an older, unpatched 26.x.

Files changed

• .github/workflows/ci.yaml: test job node-version: 24 → 26.13.0; wasm job 22 → 26.13.0
• .github/workflows/release.yaml: both node-version: 22 → 26.13.0
• site/package.json + site/package-lock.json: @types/node ^20.10.5 → ^26.6.6
• packages/workspaces/package.json + package-lock.json: @types/node ^22.0.0 → ^26.6.6
• Source-build prerequisites now say Node 26 LTS, with the existing floor kept as "works": docs/local-harness.md (22+), site/docs/local.mdx (24+), site/docs/workspace.mdx (22+)

Tested locally (Node 26.13.0, npm 11.20.0)

• node --test site/scripts/install.test.mjs: ok
• npm --prefix packages/access test: ok
• npm --prefix examples/existing-app ci + run build: ok
• npm --prefix packages/workspaces ci + run build + test: ok
• npm --prefix site ci: ok
• npm --prefix packages/client ci + run build + test: ok
• npm --prefix packages/harness-host ci: ok
• Not run locally because they need the Rust/WASM artifacts that CI builds first (target/debug/tress, site/src/wasm/pkg, site/src/server/pkg-node): examples/existing-app test, site tsc --noEmit, harness-host build/test, and the cargo/site build steps. CI covers them.

Left unchanged on purpose

• Open engines floors: packages/workspaces >=20.19, packages/harness-host >=22, packages/access and examples/existing-app >=24. They already admit 26.
• Runtime-requirement statements that mirror those floors (README "Node 22+", harness-host README/cli.mjs check, site/docs/reference.mdx, embedding.mdx, docs/setup.md, docs/fx-parity.md, packages/access/README.md, examples/existing-app/README.md).
• site/ is built by Vercel; no engines added there (Vercel does not offer Node 26 yet).
