chore: align Node 22 floor across all shipping artifacts

Reviewer (tanzhenxin) flagged five surfaces where the >=22 engine bump
leaked: SDK package metadata, web-templates engines, /doctor runtime
check, main bundler target, and SDK bundler target. Each was a separate
escape hatch letting Node 18/20 consumers install or run the artifact
on an unsupported runtime.

- packages/sdk-typescript/package.json: engines.node >=18.0.0 -> >=22.0.0
- packages/web-templates/package.json: engines.node >=20 -> >=22
- packages/cli/src/utils/doctorChecks.ts: MIN_NODE_MAJOR 20 -> 22
- esbuild.config.js: target node20 -> node22 (main CLI bundle)
- packages/sdk-typescript/scripts/build.js: target node18 -> node22 (esm + cjs)
- packages/cli/src/utils/doctorChecks.test.ts: rename test label to v22+
