Bootstrap: Default Workflow scaffold

Repo created for a reference/review of the iTelescope.net remote telescope
network. This commit copies the Default Workflow in (CLAUDE.md and docs/ from
the Default-Workflow repo), adds a .gitignore (secrets and scratch), and fills
in state/PROJECT.md with the objective: review every telescope on the network
and provide a choosing guide, using only public sources (support article and
the maintained Google Sheet; the go.itelescope.net launchpad is login-only).

+# Project setup
+
+How to start a new project on the Default Workflow. Do this once, at the beginning of
+a project, before any feature work.
+
+## 1. Create the repository
+
+- Create an empty repo on the forge (git.discworld.casa or wherever the project lives).
+- Clone it, or `git init` locally and add the remote.
+- The trunk branch is `main` unless the forge defaults to `master`; either is fine, be
+  consistent and refer to it as "the trunk" in docs.
+
+## 2. Copy the workflow files in
+
+From this Default-Workflow repo, copy into the new project root:
+
+- `CLAUDE.md` - so every session loads the workflow automatically.
+- `docs/` - the detailed workflow docs (or link to them if you prefer one source of
+  truth; copying keeps the project self contained and offline readable).
+- `templates/*` into `state/` (see next step).
+
+## 3. Create the state directory
+
+The `state/` directory is the project's memory. It replaces chat history. Copy the
+templates and fill in the project specifics:
+
+```
+state/
+  PROJECT.md      - objectives, scope, description, who it is for
+  ARCHITECTURE.md - how the system is built and why
+  DECISIONS.md    - dated log of decisions and their rationale
+  TODO.md         - what is done, in progress, and pending
+  NOTES.md        - working notes, gotchas, environment quirks
+```
+
+Fill in `PROJECT.md` first. It anchors every later session. A session that reads only
+`PROJECT.md`, `TODO.md` and `DECISIONS.md` should understand what the project is and
+what to do next.
+
+## 4. Add a .gitignore
+
+Ignore build artefacts, dependencies, secrets and local scratch. Never commit tokens
+or credentials.
+
+## 5. First commit
+
+Commit the scaffold to the trunk directly (this is bootstrap, not a feature):
+
+```
+git add .
+git commit
+```
+
+Write a full commit message describing what the scaffold contains and why. From here
+on, all work follows the [Workflow](workflow.md): a branch per feature.
