Feat v0.3.6 demo workflows + interactive demo

Four example workflow packages proving the engine end-to-end:
- Bug Report Triage: public entry, branch routing, SLA timer
- Employee Onboarding: Starlark automated stages, signoff gate
- Content Approval: multi-party signoff, revision cycle loop
- Webhook Notifier: http.post, connections fallback, delivery logging

Demo surface at /s/workflow-demo with cards, stage diagrams, Starlark
viewer, API examples, active/published status, and copyable public links.

Engine fixes: started_by in automated context, sla_seconds in package
installer, parseSnapshotStages for wrapped/legacy formats.

Platform fixes: extension SDK boot in base.html (Preact globals + boot()),
admin teams paginated response extraction, workflow adoption endpoint
(POST /teams/:teamId/workflows/:id/adopt), team-admin copyable link.

Review pass remains on roadmap for remaining UI polish.

 | Step | Status | Description |
 |------|--------|-------------|
-| Bug Report Triage | | Public entry, progressive fieldsets, severity-based branch routing, team assignment, SLA timer. Pure-manifest `.pkg`. |
-| Employee Onboarding | | Starlark automated stages (`db.insert`, `notifications.send`), signoff gate with `required_role`, rejection reroute. `.pkg` with `script.star`. |
-| Content Approval | | Multi-party signoff (quorum of 2), rejection reroute creating review cycle. `.pkg` demonstrating signoff + reroute loop. |
-| Webhook Notifier | | Starlark `http.post` + `connections.get` for outbound webhooks, delivery logging to ext_data. Proves HTTP + connections modules. |
-| Demo surface | | Browser-tier walkthrough: workflow cards, stage diagrams, Starlark viewer, "Try It" buttons, API curl examples. Auto-installed, removable. |
-| Engine context fix | | Add `started_by` to automated stage Starlark context dict (backward-compatible). |
-| Documentation | | `docs/DEMO-WORKFLOWS.md`: feature capability matrix, stage flows, API walkthrough, per-package READMEs. |
