Revive the Bubble plugin on current Uppy and Transloadit #1

Why

Kevin, 2026-10-29: revive our Bubble plugin, and modernize it the way transloadit/zapier was modernized in October 2026. Research for the partner pilot (dispatcher DSP-436) found:

• Bubble is alive. Agent 2 and a Bubble MCP launched in October 2026, and its marketplace lists about 7,600 plugins.
• Our plugin, "uppy-transloadit" (214 lifetime installs, rated 3.0), last changed in 2019. It loads Robodog v1.1.1 (deprecated) from transloadit.edgly.net, and its marketplace page no longer opens.
• A Bubble agency with maintained upload plugins already offers Transloadit as an option. Bubble builders reach for us anyway.

What

Follow the zapier repo's path, adapted to a Bubble plugin:

• Tooling. TypeScript sources with a build step that emits the code Bubble's plugin editor expects. Add Biome, vitest with coverage, Yarn 4 and Node per the repo standards, and changesets for versioning, like node-sdk and zapier.
• Code. Rebuild the element on current Uppy with @uppy/transloadit, replacing Robodog. Support a Template ID or Assembly Instructions with signatures, an upload button or Dashboard, and results exposed as Bubble states and events.
• Tests. Write unit tests for the element logic. Add an e2e test that mounts the built element in a local harness the way Bubble does, uploads a real file and waits for real results from the Transloadit API.
• CI. Run GitHub Actions on pull requests, with Dependabot. The e2e job uses opentest credentials as GitHub secrets, like zapier. For local runs, read them from ~/code/node-sdk/.env and never print them.
• Docs. Write a README, CONTRIBUTING.md with the release process and maintenance decisions, and a refreshed plugin description.
• Bubble. This repo is synced from Bubble's plugin editor ("Automatic commit from Bubble"), so code here doesn't publish by itself. Write a release script or step-by-step that puts the built element into the plugin editor. Installing in a Bubble test app, checking it there and publishing need Kevin's Bubble login.

Done when

• The modernized repo builds, tests (unit and e2e against real Transloadit) and lints in CI.
• The plugin works in a real Bubble test app.
• It's published to the marketplace with a working page, and the docs point to it.
