feat(runtime): add node-24/node-26, deprecate node(21), default new projects to node-24

- BuildRuntime enum: add node-24, node-26
- DEFAULT_RUNTIME: node → node-24
- buildImage.ts: repin node-22→22.23.1, add node-24/26 images, fix bun sidecar (node-20→node-22)
- runtime.ts: add node-24/26 cases to all switches
- config.ts: deprecation warning when runtime="node" (EOL node-21)
- init.ts: scaffold node-24 as default for new projects
