Kiln and factories-hub

Kiln is factories-hub with the changes on this page. The five skills and the state machine are the same files, at commit c941bac.

#What Kiln changes

In `factories-hub`	In Kiln
You copy the template, and do each setup step	`kiln new` does them
Paseo shows and starts sessions	Herdr and the Factory panel
GitHub Actions runs CI and the review	AWS CodeBuild
The hosted Flow reviewer	The `flow-code-review` skill and reviewdog on CodeBuild

#What Kiln adds

scripts/factory-session.sh, which starts one session for a button of the panel.
Interface skills.
Two session rules from the hub of AdonisJS: working-with-the-person.md and writing.md.

#What Kiln does not have

The factory has a worker: scripts on a factory machine that claim tasks, watch pull requests and start sessions with no person. It needs macOS and Paseo, so Kiln leaves it out, and you press the buttons. This changes these parts of the factory:

The builder. Nothing starts a build when a task is ready. You press Build.
The watcher. Nothing starts triage when a pull request changes. You press Triage. A merge does not start accept. You press Accept, so the status accepting is not used.
Drafts. Nothing makes a pull request a draft while a task is reworked. A triage comment can still say that it is a draft.
The factory identity. Sessions act on GitHub as you, not as a GitHub App.
The fleet. A fault outside a task has no fleet repository to go to.

Run builds on a machine in factories-hub explains the worker.

#Not proven yet

These parts of Kiln have not run on a real product.

kiln new building the newest Flow. Each test used an earlier tarball.
kiln new on real GitHub and AWS. Its tests used stand-ins for gh and aws.
kiln connect and kiln review as they are now. The steps inside them ran on real AWS in an earlier form.
CI on the api-monorepo kit, and the Flow review posting a finding in a monorepo.
An exploration, from intake to done.
scripts/sync-issues.mjs on a real repository. It passed a dry run.
macOS.
