feat(e2e): canary + canvas Playwright workflows; delegation mechanics

Three additions on top of 187a9bf:

1. Canary (.github/workflows/canary-staging.yml)
   30-min cron that runs the full-SaaS harness in E2E_MODE=canary: one
   hermes workspace + one A2A PONG + teardown. ~8-min wall clock vs
   ~20-min for the full run.
   Alerting is self-contained: opens a single 'Canary failing' issue on
   first failure, comments on subsequent failures (no issue spam),
   auto-closes the issue on the next green run. Labels: canary-staging,
   bug. Safety-net teardown step sweeps e2e-YYYYMMDD-canary-* orgs
   tagged today so a runner cancel can't leak EC2.

2. Canvas Playwright (canvas/e2e/staging-*.ts + playwright.staging.config.ts
   + .github/workflows/e2e-staging-canvas.yml)
   staging-setup.ts provisions a fresh org + hermes workspace (same
   lifecycle as the bash harness, just in TypeScript). staging-tabs.spec.ts
   clicks through all 13 workspace-panel tabs (chat, activity, details,
   skills, terminal, config, schedule, channels, files, memory, traces,
   events, audit) and asserts each renders without crashing and without
   'Failed to load' error toasts. Known SaaS gaps (Files empty, Terminal
   disconnects, Peers 401) are documented in #1369 and whitelisted so
   they don't fail the test — the gate is 'no hard crash', not 'no
   issues'.
   staging-teardown.ts deletes the org via DELETE /cp/admin/tenants/:slug.
   playwright.staging.config.ts separates staging from local tests so
   pnpm test in dev doesn't try to provision against staging. Retries=2
   and timeouts are longer; workers=1 because the setup provisions one
   shared workspace. Workflow uploads HTML report + screenshots on
   failure for 14 days.

3. Delegation mechanics (tests/e2e/test_staging_full_saas.sh section 10)
   Parent → child proxy test: POST /workspaces/CHILD/a2a with
   X-Source-Workspace-Id=PARENT and verify the child responds + child
   activity log captures PARENT as source. Intentionally LLM-free: the
   mechanics regression is what matters; prompt-driven delegation
   correctness belongs in canvas-driven tests.
   Also reorders teardown step to 11/11 since delegation is 10/11.

Mode gating:
   E2E_MODE=canary -> skips child workspace, HMA memory, peers,
   activity, delegation (steps 6, 9, 10 no-op). Full-lifecycle still
   runs every piece. Validated both paths via 'bash -n' syntax check
   after each edit.

Secrets requirement unchanged (same two secrets as 187a9bf):
  MOLECULE_STAGING_SESSION_COOKIE, MOLECULE_STAGING_ADMIN_TOKEN.
