Fix exe.dev sandbox installs for gemini/opencode local adapters (#5737)

## Thinking Path

> - Paperclip orchestrates AI agents for zero-human companies, including
running adapter CLIs inside remote sandboxes
> - The QA matrix in PAPA-316 spins up local-runtime adapters
(claude/gemini/opencode) against both SSH and the new exe.dev sandbox
provider, and "Test" exercises the same install + probe path the real
runtime uses
> - On exe.dev the QA matrix failed at three different points:
SSH/sandbox secret refs would not resolve, gemini-local could not find
npm, and opencode-local installed a binary that was not on the
probe-shell PATH
> - These are all environment-shape issues the runtime should handle,
not regressions in any individual adapter, so they need to be fixed in
the shared install/resolve layer before the matrix can pass
> - This pull request wires the environment id through to secret-ref
resolution, bootstraps npm from a portable Node tarball when the sandbox
image lacks Node, and symlinks the opencode binary into a directory that
non-login shells see
> - The benefit is that the QA matrix passes end-to-end on exe.dev, and
any future sandbox provider that ships without Node or relies on rc-file
PATH wiring gets the same fixes for free

## What Changed

- `server/src/services/environment-execution-target.ts`: pass the
environment `id` into `resolveEnvironmentDriverConfigForRuntime` for
both the sandbox and SSH branches, so `privateKeySecretRef` /
sandbox-provider secret refs (e.g. exe.dev `apiKey`) can resolve against
the secret store at runtime instead of throwing `Runtime secret
resolution requires an environment id`.
- `packages/adapter-utils/src/sandbox-install-command.ts`: extend
`buildSandboxNpmInstallCommand` with an `ENSURE_NPM_PREAMBLE` that, when
`npm` is missing, downloads a portable Node v22 tarball into
`$HOME/.local` and sets `PAPERCLIP_NPM_BOOTSTRAPPED=1` so the install
step skips sudo (sudo's `secure_path` would lose the freshly-installed
`npm` in `$HOME/.local/bin`). Distro-packaged Node from apt-get is
intentionally avoided because it tends to be too old to parse modern JS
syntax used by `@google/gemini-cli`.
- `packages/adapters/gemini-local/src/index.ts`: switch the hardcoded
`npm install -g @google/gemini-cli` to `buildSandboxNpmInstallCommand`,
so gemini-local picks up the same sudo-aware + npm-bootstrap behavior as
the other local adapters.
- `packages/adapters/opencode-local/src/index.ts`: append a step to the
install command that symlinks `$HOME/.opencode/bin/opencode` into
`$HOME/.local/bin`. The upstream installer only adds `~/.opencode/bin`
to PATH via `~/.bashrc`, which non-login `sh -c` probe invocations do
not source.
- `packages/adapter-utils/src/sandbox-install-command.test.ts`: cover
the new preamble plus the unchanged root/sudo/user-prefix branches.

## Verification

- `cd packages/adapter-utils && npm test -- sandbox-install-command`
(passes; new "bootstraps npm from a portable Node tarball when missing"
case is included).
- Manual: ran the in-app `Test` action against the QA matrix dev
instance for `QA exe.dev Claude`, `QA exe.dev Gemini`, and `QA exe.dev
OpenCode` — all three now report `status=pass` including the hello
probe. `QA SSH Claude` also passes; without the environment-id fix, SSH
resolution threw before the wrapper / install fixes could run.
- Suggested reviewer check: re-run the matrix on a fresh exe.dev
environment and confirm the install step no longer hits `npm: command
not found` for gemini and the opencode probe no longer hits `opencode:
command not found`.

## Risks

- Low/medium. The npm bootstrap pins Node `v22.11.0` from
`nodejs.org/dist`; if that URL becomes unreachable the install will fail
with a clear `curl` error rather than corrupting state. The bootstrap
path is only taken when `npm` is genuinely missing, so existing sandbox
images that ship with Node are unaffected.
- The opencode symlink uses `ln -sf` into `$HOME/.local/bin`, which is
created with `mkdir -p`; idempotent on re-install.
- The `id` change is a strict additive: callers previously got
`undefined` and only the secret-ref code paths actually read it. No
behavior change for environments without secret refs.

## Model Used

- Claude (Anthropic), `claude-opus-4-7`, with extended thinking and tool
use enabled. Iterated through the Paperclip QA matrix harness; no other
model assisted.

## Checklist

- [x] I have included a thinking path that traces from project context
to this change
- [x] I have specified the model used (with version and capability
details)
- [x] I have checked ROADMAP.md and confirmed this PR does not duplicate
planned core work
- [x] I have run tests locally and they pass
- [x] I have added or updated tests where applicable
- [ ] If this change affects the UI, I have included before/after
screenshots (n/a — runtime/install path only)
- [x] I have considered and documented any risks above
- [x] I will address all Greptile and reviewer comments before
requesting merge
