Nicky LeachandClaude Opus 5.5 14cb69245f fix(projects): do not offer a single project storage option (#20875)
## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work
> - A project uses one workspace storage owner. The user chooses it when
they create the project.
> - The **Available in** selector shows the storage owners that the user
can choose.
> - Sometimes the default environment cannot be used, and only one
storage owner is available. In that case, the dialog shows a selector
with only one option. The user must select it before they can create the
project.
> - A selector with only one option is not a real choice.
> - This pull request uses the only available storage owner as the
default. The selector appears only when the user has two or more
options.
> - The benefit is that project creation asks for a choice only when
there is one.

Refs #20835

**What happened?**
An example is an instance in managed-sandbox-only mode that has the
agent-computer plugin but no managed sandbox. The local environment is
hidden, and the managed-only rule finds no default. The
project-environments endpoint returns one storage group and an error.
The new project dialog shows **Available in** with only one option and
disables **Create project** until the user selects it. An API request
without `environmentId` fails with `project_environment_unavailable`.

**What did you expect?**
When only one storage owner is available, the project uses it. No
selector appears.

**Steps to reproduce**
1. Turn on `enableManagedSandboxOnly`. Install the agent-computer
plugin. Do not add a sandbox environment.
2. Open **Create project**.
3. See an **Available in** selector with one option, and a disabled
**Create project** button.

## What Changed

- `projectEnvironmentOptions`: when the configured default is
unavailable and only one storage group exists, the first environment of
that group becomes `defaultEnvironmentId`, and `error` is null. When two
or more groups exist, an unavailable default still produces the error.
The server does not guess.
- Project create uses the same default, so an API request without
`environmentId` now succeeds in the single-group case.
- `NewProjectDialog` shows the selector only when `groups.length > 1`.
- Tests:
- A new server test covers managed-only mode with only the
agent-computer environment.
- A new server test covers an unavailable default with two storage
groups (the server still refuses to guess).
- The archived-default test now expects the server to use the only
remaining storage.
  - A new UI test checks that the dialog never shows one option.
- Docs: `doc/project-environment-compatibility.md` and
`docs/api/goals-and-projects.md`.

## Verification

- `pnpm vitest run src/__tests__/project-environments.test.ts` in
`server/`: 16 passed.
- `pnpm vitest run src/components/NewProjectDialog` in `ui/`: 12 passed.
- `tsc --noEmit` in `ui/`: clean.
- Server `tsc` reports 9 errors on this machine. None are in the changed
files. They are in `packages/adapter-utils` and a native-runtime test,
because local dependencies are stale. CI typechecks with a fresh
install.

## Risks

- Low risk. The change applies only when the default is unavailable and
exactly one storage group exists. In that case, the server picks the
group that the user would have had to choose anyway. Run placement does
not depend on the project, so this does not change where runs execute.
- No migration.

## Model Used

- Claude Opus 5.5 (`claude-opus-5-5`) in Claude Code, with tool use
(shell, file edits, test runs).
