Summary

Owner ruling: we don't need to test our scripts, and scripts/ carried
repro/lib/git-hooks/e2e clutter that doesn't belong there.

• Deletes every scripts/*.test.* (top level and scripts/e2e/),
  including tests of the harness, db-gate, list-suites, and db-setup.
• Deletes scripts/repro/, scripts/lib/ (its only file,
  publishable-packages.ts, had no consumers — deleted rather than
  inlined), scripts/git-hooks/, scripts/hooks-install.ts (and the
  hooks:install/prepare package.json scripts),
  scripts/backfill-principal-keys.ts (a one-off backfill — cutovers
  are breaking, no backfills), scripts/generate-tsconfig-references.ts
  (unreferenced by anything, including typecheck.ts's comments, now
  updated), and scripts/e2e/docker-sidecar-smoke.ts +
  scripts/e2e/list-suites.ts (unreferenced).
• Creates root e2e/ and moves the real harness/support files there:
  harness.ts, db-gate.ts, database-url.ts,
  noop-inference-server.ts, workflow-source.ts,
  browser/walkthrough.ts. scripts/db-setup.ts stays in scripts/;
  imports were fixed accordingly.
• Updates every scripts/e2e/... import across the repo (~30 files:
  packages/, apps/, tools/, docs, .gitignore, .github/workflows/ci.yml)
  to e2e/....
• Root package.json: test is now bun run scripts/run-all.ts test
  (no more bun test ./scripts/*.test.ts); test:e2e is
  bun test e2e --max-concurrency=1; e2e added to the lint, fmt,
  and fmt:check path lists.

Per-suite keep/delete reasoning

Checked every suite's routes/imports against what apps/hub/src/server.ts
actually mounts and what files still exist on main:

• smoke-auth — kept, moved to e2e/. Only touches
  /api/auth/* and /api/me/principals, both still mounted; imports
  resolve.
• smoke-webhook — kept, moved to e2e/. Uses
  POST /api/tenants, the native workflow-deploy route, and
  @corbits/webhook-triggers's ingress route — all still mounted.
  packages/tool-registry-publish, packages/hub-api-client, and
  agents/assistant all still exist and export what it imports.
• walking-skeleton — kept, moved to e2e/. Same route/import
  surface as smoke-webhook (tenant creation, git-backed workflow asset
  publish, native deploy); still current.
• t3-github-roundtrip.proof — kept, moved to e2e/. Calls
  /api/tenants/:id/connections/github/complete and .../disconnect,
  which packages/connections/src/connect-github-routes.ts still
  serves.
• smoke-chat — deleted. Calls
  POST /api/tenants/:id/chat/workbenches and sibling
  chat/workbenches/* routes; apps/hub/src/server.ts no longer mounts
  any chat/workbenches route — chat is now mail over
  @corbits/mailbox. Dead suite, not moved.
• smoke-onboarding — deleted. It already only exercises stock
  POST /api/tenants plus a benchless-signup assertion — no route or
  import is stale, but it duplicates the tenant-creation hop that
  smoke-webhook and walking-skeleton already cover end to end, and it
  was written specifically to prove the (now long-settled) provisioning
  cutover. Kept it would just be a slower, redundant re-run of a step
  the surviving suites already assert on.

Test plan

• bun run typecheck
• bun run lint
• bun run fmt (clean, no diff after)
• bun run test — 766 pass / 0 fail across all packages. The one
  non-zero exit is @intx/hub-agent (vendor/intx/hub-agent)
  reporting "0 test files matching" — a pre-existing vendored
  package with no test files, unrelated to this change.
