Devin FoleyandPaperclip 0c2ec7deb4 Fix sandboxed Claude and Codex probe behavior (#8775)
## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work.
> - Local adapters are the bridge between Paperclip's control plane and
provider CLIs such as Claude Code and Codex.
> - Those adapters can run either on the host machine or inside a
remote/sandbox execution target.
> - Sandbox probes need to validate the same auth/config path that real
sandbox execution will use.
> - The previous probe paths could surface misleading Claude errors,
rely on host-only Codex state, or upload far more Codex home state than
the probe needed.
> - This pull request fixes the Claude and Codex sandbox probe/runtime
behavior together while keeping provider-specific sandbox image work out
of scope.
> - The benefit is faster, clearer adapter health checks that better
match real sandbox execution.

Bug report:

**What happened?**

Sandboxed Claude/Codex adapter tests could diverge from real runtime
auth/config behavior. Claude sandbox probes could show the leading
stream init line instead of the real final error, and Codex sandbox
probes could upload full managed home state or mask a sandbox-local
login with an empty uploaded `CODEX_HOME`.

**Expected behavior**

Sandbox probes should exercise the remote runtime contract, preserve
useful sandbox credentials, avoid relying on unrelated host state, and
report actionable probe failures.

**Steps to reproduce**

1. Configure a remote/sandbox execution target for `claude_local` or
`codex_local`.
2. Run the environment Test/probe path where host credentials differ
from the sandbox's runtime credentials or the managed Codex home
contains session history.
3. Observe that probe behavior can differ from the actual sandbox
runtime path or surface an unhelpful Claude stream initialization line.

**Paperclip version or commit**

Current `master` before this PR, based on `4a2447da3`.

**Deployment mode**

Local development/control-plane deployment with remote sandbox execution
targets.

## What Changed

- Made Claude sandbox Test probes materialize the same Paperclip-managed
Claude config seed path used by sandbox execution.
- Preserved sandbox-local Claude credentials when materializing remote
Claude config and expanded auth-required detection for `/login` API-key
failures.
- Improved Claude hello-probe diagnostics so the final result/error is
surfaced instead of the unhelpful stream init event, with transient
upstream failures downgraded to warnings.
- Changed Codex probe behavior to upload only minimal auth/config files
instead of the full managed `CODEX_HOME`.
- Let Codex sandbox probes leave `CODEX_HOME` unset when the host has no
credentials, so pre-authenticated sandbox images can be tested directly.
- Excluded bulky host-local Codex session/shell state from sandbox
runtime home uploads.
- Switched the Codex local default model away from the
ChatGPT-unsupported `gpt-5.3-codex` option.
- Added regression coverage for Claude parsing/probe paths, Codex
adapter metadata/argument/probe behavior, and server-level Claude
sandbox environment behavior.

- `git diff --check`

## Risks

- Adapter configuration behavior is sensitive to local vs sandboxed
execution mode, so review should focus on environment detection,
argument construction, and any state written during probe/test runs.
- The Codex default-model change may affect newly created agents that
rely on the adapter default instead of an explicit model.
- Excluding Codex session/shell state from sandbox uploads should be
safe for fresh sandbox runs, but reviewers should confirm no runtime
resume path depends on that host-local state.
- Provider-specific setup/capture behavior is intentionally left to
separate work.

## Model Used

OpenAI GPT-5 Codex via Paperclip `codex_local`; tool-enabled local
coding session with terminal access. Context window size was not exposed
by the runtime.
