feat(ms-ai-architect): wire kb-update test suite into run-e2e dispatch [skip-docs]

Step 12 — adds --kb-update flag to tests/run-e2e.sh and a Bash 3.2-compatible
shim test-kb-update.sh that runs `node --test tests/kb-update/*.test.mjs`
(shell-glob form; Node 25 rejects directory-form arguments). Shim translates
node --test exit code + parsed pass/fail counts into the e2e-helpers.sh
suite counters (init_suite/print_summary).

Verification:
- Playground baseline 271 PASS unchanged before/after edit
- bash tests/run-e2e.sh --kb-update: exits 0, 110/110 inner tests pass
- bash tests/run-e2e.sh --all: kb-update suite included
- Pre-existing ROS-fixture absence (tests/fixtures/ros-analysis/) is
  unrelated to this change and remains for separate handling

Wave 5 of 7 in v1.12.0 auto-KB-update plan.
Plan: .claude/projects/2026-05-04-kb-update-fork-and-own/plan.md (Step 12)
