* fix(test): make unit tests hermetic against host config and build state
Two host-state leaks made the full suite fail deterministically on developer
and agent machines while CI stayed green:
- Built checkouts: bundled-plugin manifest discovery prefers dist/extensions,
which by design excludes externalized official plugins (e.g. qwen). Tests
that depend on manifest-driven endpoint classification (DashScope cases in
media-understanding and model-compat) failed in any checkout after
pnpm build. test-env now pins OPENCLAW_BUNDLED_PLUGINS_DIR to the source
extensions tree (with the vitest trust opt-in) so discovery matches CI
regardless of local build state; discovery tests keep managing the env
per case.
- unit-fast shards: setupFiles was empty, so auto-curated tests that read
config saw the developer's real ~/.openclaw/openclaw.json; any key the
branch schema rejects failed those tests. unit-fast and
unit-fast-fake-timers now load a minimal env-isolation setup
(test/setup.env.ts) that installs the isolated test home without the
shared setup's module mocks.
* test: update unit-fast config contract for env-isolation setup
* fix(test): force unit-fast hermetic env isolation
