feat(claude): environment-aware test-environment probe and claude-local CI coverage (#10833)

## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work
> - The claude_local adapter runs Claude Code on sandbox execution
targets, and operators verify an agent's configuration with the
test-environment probe before running it
> - Real runs merge the selected environment's env vars (secret refs
included) under the agent's adapter config env, but the probe built its
config from the adapter config alone — so environment-level auth worked
in runs while the Test button reported missing auth, and a dropped
secret binding passed silently
> - The claude env-test hints also did not recognize
`CLAUDE_CODE_OAUTH_TOKEN` even though the CLI accepts it, and a hello
probe that hit the subscription usage limit reported a hard failure
although authentication worked
> - Separately, the claude-local package test suites were absent from
the CI project list, so two suites drifted broken without notice
> - This pull request makes the probe resolve the same layered env as a
real run, adds the missing auth hint, classifies usage-limit probe
results as a warning, repairs the drifted suites, and turns the
claude-local project on in CI
> - The benefit is a Test button that tells the truth about
environment-level configuration, and a test suite that actually gates
the claude-local adapter

## Linked Issues or Issue Description

No public issue exists; related open PRs: Refs #9488 (recognizes
CLAUDE_CODE_OAUTH_TOKEN in environment checks — overlaps with the
auth-hint portion of this PR via a differently named check; it does not
cover the environment-envVars probe merge, the usage-limit
classification, or the CI coverage), Refs #9933 (live credential
validation in environment checks — complementary, no file-level conflict
with the route change).

The underlying problem, following the enhancement template:

**Current behavior**

The test-environment route builds the probe config from the agent's
adapterConfig only. Real runs merge the selected environment's envVars
under the agent env, so environment-level env vars (including auth such
as `ANTHROPIC_API_KEY` or `CLAUDE_CODE_OAUTH_TOKEN` bound as environment
secrets) work in runs while "Test environment" cannot see them, and a
missing secret binding passes silently. The claude env-test hints do not
recognize `CLAUDE_CODE_OAUTH_TOKEN`. A hello probe that hits the
subscription usage limit reports a hard `claude_hello_probe_failed`. The
claude-local package test suites do not run in CI, and two of them are
stale.

**Proposed behavior**

The probe resolves the selected environment's envVars
(environment-consumer secret bindings included) and merges them under
the agent config env with the run-path precedence; missing bindings
surface as an explicit error check that fails the test. The env-test
emits a `claude_oauth_token_configured` info check when that variable is
set. Usage-limit probe results classify as a
`claude_hello_probe_usage_limited` warning because auth works and only
the usage window is spent. The claude-local suites run in CI. Docs state
the resulting facts.

**Reason and benefit**

The Test button should tell the truth: it previously contradicted run
behavior for environment-level configuration and hid broken secret
bindings. Enabling the package suites in CI prevents further silent
drift — two suites were already broken on master without anyone
noticing.

**Breaking changes**

None. Runs are unchanged. The probe route only adds env layers and
checks; setups without environment envVars behave exactly as before.

## What Changed

- `server/src/routes/agents.ts`: the test-environment route resolves the
selected environment's envVars (forbidden keys stripped,
environment-consumer secret context) and merges them under the agent
adapterConfig env, mirroring `resolveExecutionRunAdapterConfig`
precedence. Missing secret bindings are skipped, reported as an
`environment_env_binding_missing` error check, and fail the test —
matching the `ConfigurationIncompleteFailure` a real dispatch would
raise.
- `packages/adapters/claude-local/src/server/test.ts`: new
`claude_oauth_token_configured` info hint between the API-key warning
and the subscription fallback; hello-probe classification gains a
`claude_hello_probe_usage_limited` warning for provider-quota results
(previously a hard `claude_hello_probe_failed`).
- `scripts/run-vitest-stable.mjs`: add
`@paperclipai/adapter-claude-local` to `nonServerProjects` so CI runs
the package suites.
- `packages/adapters/claude-local/src/server/execute.remote.test.ts`:
assert both runtime asset syncs (skills and mcp-config); the suite
predated the mcp-config asset.
- `packages/adapters/claude-local/src/server/test.probe.test.ts`:
usage-limit fixture now expects the usage-limited warning; new fixture
covers the genuine transient path (529 overloaded); new tests cover the
token hint and API-key precedence.
- `server/src/__tests__/agent-test-environment-routes.test.ts`: new
tests for the env merge (agent wins on conflict, forbidden key
filtered), missing-binding reporting, and the no-execution-target
fallback path.
- `docs/adapters/claude-local.md`, `docs/adapters/overview.md`: state
the auth-input facts (API key or oauth token wins over stored logins;
snapshot-owns-auth applies when neither is configured) and describe the
environment-aware Test behavior.

## Verification

- `npx vitest run --project @paperclipai/adapter-claude-local` — 131
tests pass (both drifted suites repaired; they fail on master today).
- `npx vitest run
server/src/__tests__/agent-test-environment-routes.test.ts` — 7 tests
pass.
- `node --test ./scripts/__tests__/run-vitest-stable-shard.test.mjs` —
passes with the added project.
- `pnpm typecheck` in `server/` and `packages/adapters/claude-local/` —
clean.

## Risks

- Low risk. The run path is untouched; the probe route change is
additive and inert when the environment has no envVars.
- The probe now performs environment-consumer secret resolution at test
time; access is authorized per binding exactly as at run time, and the
audit consumer is the environment (as before for adapter-config
resolution).
- Enabling the claude-local project in CI adds about 2 seconds of vitest
wall time to the general workspaces group and could surface future
regressions in that package — which is the point.

## Model Used

Claude Fable 5 (`claude-fable-5`), extended thinking enabled, agentic
tool use via Claude Code (CLI).
