feat(deno): migrate accessibility-everywhere tools/ (7/8 manifests, standards#253 longtail)

[hyperpolymath]

Summary

Workspace-style migration covering 7 of 8 npm manifests. The eighth (tools/browser-extension/package.json) is Class C — browser-extension packaging requires the npm-published archiver library at build time. Same Class C pattern as VSCode extensions / Office add-ins.

Migrated

Manifest	Class	New	Imports
/package.json	workspace-root	extend /deno.json	workspace field with 6 ReScript tools; tasks orchestrate setup/build/test/docker
tools/safe-dom/package.json	B	tools/safe-dom/deno.json	rescript@^12, @rescript/core@^1.6
tools/cli/package.json	B	tools/cli/deno.json	rescript, commander, chalk, ora, cli-table3, fs-extra
tools/github-action/package.json	B	tools/github-action/deno.json	rescript, @actions/core, @actions/github
tools/monitoring-api/package.json	B	tools/monitoring-api/deno.json	rescript, express, cors, helmet, express-rate-limit, compression, dotenv, joi, uuid
tools/stale/packages/core/package.json	B	tools/stale/packages/core/deno.json	rescript@^11.1 (preserved), @rescript/core@^1.5, arangojs, dotenv
tools/stale/packages/scanner/package.json	B	tools/stale/packages/scanner/deno.json	rescript@^11.1 (preserved), axe-core@^4.8, playwright, puppeteer

All Class B tools use deno run -A --node-modules-dir=auto npm:rescript@^<version> for build/clean/dev (rescript's install lifecycle requires resolvable node_modules).

Deferred (Class C — host-required)

• tools/browser-extension/package.json — depends on archiver (npm-only zip lib) for Chrome/Firefox packaging; axe.min.js is copy-source-pathed from node_modules at build time. Class C pattern (host-required npm scaffolding). Tracked as carve-out candidate for hypatia rule extension (per-repo follow-up).

The root build:browser-extension task emits a documentation message instead of orchestrating, so deno task build:browser-extension does not silently fail.

Test plan

• deno task build chains cli + safe-dom + scanner builds
• Each tool's deno task build produces equivalent .mjs/.bs.js output to prior bare rescript
• deno task setup invokes the arangodb setup script

Per per-repo follow-up tracker for standards#253 (campaign closed 2026-05-31, longtail tracked in project_estate_npm_to_deno_2026_05_28.md).
