DottaandClaude 200c6e40e2 fix(native): restart a bootstrap whose Runner suspended before the provider opened (#20691)
## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work.
> - When a native run's first provider start fails before any session
opens, Paperclip retries the bootstrap on the same run. Durable
controller evidence proves that no provider session or provider event
exists.
> - A remote sandbox keeps the Runner state inside the workspace. A
replacement sandbox gets that state back when the saved workspace is
restored.
> - When the provider refused `session.open` (for example an Anthropic
429), the Runner still suspended cleanly. Its state says `suspended`,
but the provider state has no session identity.
> - The same-run restart handled a Runner that never suspended. It did
not handle a Runner that suspended before the provider opened a session.
It failed with `runner_harness_state_mismatch:
provider_identity_incomplete (provider_not_suspended)`, and the task
showed "Recovery needed" without Retry.
> - This pull request lets that proven restart set the unopened session
aside and start the provider again.
> - The benefit is that a rate-limited provider start continues by
itself after the limit resets.

## Linked Issues or Issue Description

Refs #20627 and #20683 (other restore paths). This PR changes only the
same-run bootstrap restart.

**What happened?**

Two ACPX Claude tasks on remote Daytona sandboxes, on staging:

1. The first attempt sent `session.open`. ACPX rejected it with
`classification=provider_rate_limit` (Anthropic 429). The Runner exited
with `lifecycle=suspended`.
2. Paperclip recorded `recoveryMode: bootstrap_retry`,
`providerSessionEstablished: false`, `providerEventsExist: false`, and a
retry after the limit reset.
3. One hour later the retry ran as `bootstrap_incomplete` on the same
run, in a new sandbox with the saved workspace restored.
4. Host preparation inspected the restored Runner state. The Runner was
`suspended`, but the provider had no session identity. The inspection
threw `provider_identity_incomplete (provider_not_suspended)` before the
bootstrap restart branch ran.
5. The run failed. The task stopped at "Recovery needed" with only
inspect actions.

**Expected behavior**

The restart sets the unopened session aside and opens a new provider
session, as it already does for a Runner that never suspended.

**Steps to reproduce**

1. Restart a remote run as `bootstrap_incomplete` with a proven
bootstrap restart.
2. Give the sandbox a Runner state for this run with `lifecycle:
suspended` and a provider state with no session identity.
3. Prepare the host. On `master` it throws
`runner_harness_state_mismatch: provider_identity_incomplete`.

The new `interrupted_bootstrap_unopened` cases of `bootstraps only an
untouched provider session in a $outcome workspace lease` run these
steps for a created and a resumed lease.

**Paperclip version or commit**

`master` at `7435abcc63`.

## What Changed

- During host preparation, a Runner state that is suspended with no
provider session identity returns the new incomplete reason
`provider_unopened`, but only when all of these hold:
  - the run is restarting as `bootstrap_incomplete`;
  - the state belongs to this same run;
- the controller already recorded the bootstrap restart proof (its
durable journal shows no provider turn, and the old Runner is stopped or
absent).
- the provider state is the one saved before any session opened
(`remoteProviderStateNeverOpened`): `prepared`, no session or identity,
no turn in progress, no unconfirmed exit. Only ACPX and Codex-family
states qualify.
- The created-lease and resumed-lease restart branches share one check
(`restartableBootstrapState`) and accept `provider_unopened` exactly
like `not_suspended`. They move the old session aside and claim a new,
untouched session root.
- Every other case still throws `provider_identity_incomplete`: another
run's state, a restart without the proof, a normal resume, and close
checkpointing.

## Verification

- `pnpm --filter @paperclipai/server exec vitest run
src/services/native-runtime/native-session-executor.test.ts -t
"bootstraps only an untouched provider session"`: 47 passed.
- Red on `master`: the `created` and `resumed`
`interrupted_bootstrap_unopened` cases fail with
`runner_harness_state_mismatch: provider_identity_incomplete
(identity_binding)`. Green with this change.
- Fail-closed cases stay red-proof:
`interrupted_bootstrap_unopened_unproven` (no restart proof) and
`interrupted_bootstrap_unopened_other_run` (another run's state) still
throw.
- Full `native-session-executor.test.ts` and `pnpm --filter
@paperclipai/server typecheck` pass.

## Risks

- Low risk. The new branch needs the same proof that already authorizes
a fresh bootstrap for a Runner that never suspended. The proof comes
from the controller's durable journal, not from the sandbox.
- The normal path is unchanged and has no added wait.
- Not proven live: I did not confirm on staging that the controller
recorded the restart proof for these runs. If it did not, the run still
fails closed as before.
