## Summary
Refresh the vendored Sandboxes cookbook and OpenAPI reference from
upstream.
Removes standalone MCP gateway start/stop documentation, imports
upstream authentication and timeout examples, auto-resume readback
guidance, and network-policy selector updates, and regenerates the API
presentation data.

API generation introduced in #26048 added roughly five minutes to site
builds: median successful main-branch build-workflow duration rose from
4m 05s to 8m 48s across September 3–25. The pre-build command took 4m
41s–4m 53s in each of four jobs on the merge commit.
Vendor the generated presentation model in `data/api-reference.json`,
mark it as generated, and let Docker, Netlify, and local Hugo builds
consume it directly. Keep the existing rendered-output checks.
Move generator tests, strict spec validation, and a byte-for-byte
regeneration check into `docker buildx bake validate-api-reference`,
inheriting the shared Docker base stage. The target uses the pinned
Vacuum release binary with Dockerfile ADD checksum verification and
archive extraction instead of compiling Vacuum from source. The existing
build workflow runs this target alongside the other validation matrix
entries. Only this matrix entry is advisory; its failures do not block
site builds or deployment.
Validated locally with the Docker target, rejection of deliberately
stale data, repeatable generation across directories, a production Hugo
build and verification of 453 API HTML/Markdown page pairs, workflow
syntax checks, and scoped documentation lint. The prebuilt-binary CI
check passed in 1m 40s, down from 5m 15s with source compilation. Remote
layer-cache settings were subsequently removed; local Go cache mounts
remain.
