DottaandPaperclip 6080daf262 fix(runner): start native OpenCode without postinstall (#15702)
## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work.
> - Paperclip Runner starts a qualified OpenCode runtime for native
tasks.
> - The default launch path uses a file populated by OpenCode's
postinstall script.
> - Package managers can skip that script and leave a text placeholder.
Native task startup then fails with `spawn ENOEXEC` before the model
request.
> - This pull request resolves the declared platform package directly
and includes the pinned runtime in the published server dependency
graph.
> - Users can run native OpenCode tasks after a normal install without
global commands or manual dependency repair.

## Linked Issues or Issue Description

**What happened?**

Native OpenCode tasks fail at session startup when dependency
postinstall is skipped. The Runner selects
`opencode-ai/bin/opencode.exe`, which contains a text placeholder. The
published server also lacks the OpenCode runtime dependency used by its
vendored Runner.

**Expected behavior**

Paperclip starts the qualified platform binary installed by the package
manager. macOS uses a Mac binary. No manual postinstall command is
needed.

**Steps to reproduce**

1. Install dependencies with lifecycle scripts disabled.
2. Configure a native OpenCode agent with an OpenRouter model and valid
credentials.
3. Assign a task. The previous default fails before any model request.

Related work: #15682 fixes HTTP transport registration. #15422 includes
compatible OpenCode resolution in a broader agent setup change. This PR
isolates the runtime repair for current users.

## What Changed

- Resolve pinned OpenCode platform packages through the module
dependency graph in source, standalone, and vendored server layouts.
- Check package identity, version, platform, executable containment, and
execute permission. Preserve verified executable launch profiles.
- Use the resolver for new and resumed native sessions. Reject missing
remote pack executables before controller dependency lookup.
- Declare `opencode-ai@1.18.34` as a published server dependency. Leave
platform selection to the consumer's package manager.
- Check remote paths for the selected provider only. An unused OpenCode
path must not reject a Pi run on macOS.
- Add skipped-postinstall and invalid artifact regressions. Document
automatic runtime selection.

## Verification

- Regression tests fail with the previous default path and pass with
platform resolution.
- Source, standalone, and vendored layout fixtures cover Apple Silicon,
Intel Mac, and Linux x64 baseline packages.
- A fresh npm install with `--ignore-scripts` resolves the macOS
executable and reports `1.18.34`. The placeholder remains unchanged.
- Live browser test on Apple Silicon: a native
OpenCode/OpenRouter/DeepSeek task ran shell arithmetic, created and
uploaded a verified 23-byte file, and completed. A follow-up ran shell
arithmetic and completed using the same session. Both runs committed
successfully while the wrapper remained broken.
- `pnpm -r typecheck` and `pnpm build` passed. All 269 affected Runner
tests and 8 server packaging tests passed. `pnpm test:run` encountered
15 initial database-heavy failures; all 15 passed on an isolated group
rerun. The redundant local run was then stopped after the matching
server and workspace CI suites passed. All final-head checks passed (56
passed, 2 skipped); its unrelated chat-retry browser assertion passed on
one rerun. An additional local repeat could not start its temporary
server within the startup timeout. Greptile reviewed the final head at
5/5 with no open findings.

## Risks

- Native runtime resolution requires the pinned optional platform
package. Installations that omit optional dependencies fail with an
explicit runtime error.
- Supported native targets remain Apple Silicon, Intel Mac, and Linux
x64. This change does not qualify another platform.
- Published server installations now install the OpenCode dependency.
Remote provider packs retain their verified executable paths and
digests.
- No schema changes or agent configuration migration.
- Repository policy assigns `pnpm-lock.yaml` to CI. PR CI refreshes
dependency resolution before frozen installs, and the master workflow
updates the tracked lockfile. This PR leaves the tracked lockfile
unchanged.

## Model Used

- OpenAI GPT-6 through Codex, with reasoning, tool use, and code
execution. The session does not expose the exact GPT-6 variant or
context window.
- Live verification used OpenRouter `deepseek/deepseek-v4-flash-0731`;
it did not author this patch.
