Add cursor sandbox support and fix SSH workspace sync (#4803)
## Thinking Path

> - Paperclip orchestrates AI agents for zero-human companies
> - Agents can run inside sandboxed environments like E2B, or on remote
hosts via SSH
> - The cursor adapter needs to resolve `cursor-agent` inside sandbox
environments where it's installed in `~/.local/bin`
> - But when using the default `agent` command on a sandbox target, the
adapter didn't know to look in `~/.local/bin/cursor-agent`, causing
"command not found" failures
> - Additionally, repeated SSH runs failed because `git checkout` during
workspace sync conflicted with leftover `.paperclip-runtime` files from
previous runs
> - This PR adds sandbox-aware command resolution for cursor and fixes
the SSH workspace sync conflict
> - The benefit is cursor works in E2B sandboxes out of the box, and
repeated SSH runs don't fail on workspace sync

## What Changed

- `cursor-local`: Added `prepareCursorSandboxCommand` — on sandbox
targets, reads the remote `$HOME`, prepends `~/.local/bin` to PATH, and
prefers `~/.local/bin/cursor-agent` when the default command is
requested; tightened the sandbox command probe to validate the binary
exists before launching; preserves explicit custom command overrides
- `adapter-utils/ssh.ts`: Added `--force` to git checkout in SSH
workspace sync to handle `.paperclip-runtime` untracked file conflicts
from previous runs

## Verification

- `pnpm test` — all existing and new tests pass, including cursor
sandbox probe, sandbox execution, and custom command override tests
- `pnpm typecheck` — clean
- Manual: configure an E2B environment, run a cursor-local task, verify
it resolves cursor-agent from the sandbox install path

## Risks

- Low-medium. The `--force` flag on git checkout could discard
uncommitted changes in the remote workspace, but the workspace is
managed by Paperclip and should not contain user edits.

## Model Used

Codex GPT 5.4 high via Paperclip.

export const agentConfigurationDoc = `# cursor agent configuration
Adapter: cursor
Use when:
- You want Paperclip to run Cursor Agent CLI locally as the agent runtime
- You want Cursor chat session resume across heartbeats via --resume
- You want structured stream output in run logs via --output-format stream-json
Don't use when:
- You need webhook-style external invocation (use openclaw_gateway or http)
- You only need one-shot shell commands (use process)
- Cursor Agent CLI is not installed on the machine
Core fields:
- cwd (string, optional): default absolute working directory fallback for the agent process (created if missing when possible)
- instructionsFilePath (string, optional): absolute path to a markdown instructions file prepended to the run prompt
- promptTemplate (string, optional): run prompt template
- model (string, optional): Cursor model id (for example auto or gpt-5.3-codex)
- mode (string, optional): Cursor execution mode passed as --mode (plan|ask). Leave unset for normal autonomous runs.
- command (string, optional): defaults to "agent"
- extraArgs (string[], optional): additional CLI args
- env (object, optional): KEY=VALUE environment variables
Operational fields:
- timeoutSec (number, optional): run timeout in seconds
- graceSec (number, optional): SIGTERM grace period in seconds
Notes:
- Runs are executed with: agent -p --output-format stream-json ...
- Prompts are piped to Cursor via stdin.
- Sessions are resumed with --resume when stored session cwd matches current cwd.
- Paperclip auto-injects local skills into "~/.cursor/skills" when missing, so Cursor can discover "$paperclip" and related skills on local runs.
- Paperclip auto-adds --yolo unless one of --trust/--yolo/-f is already present in extraArgs.
- Remote sandbox runs prepend "~/.local/bin" to PATH and prefer "~/.local/bin/cursor-agent" when the default Cursor entrypoint is requested, so standard E2B-style installs do not need hardcoded absolute command paths.
