Create "community governance templates" gallery for Satya

Satya_AI is designed as a source of truth and governance layer for autonomous agents, but new users often ask: *"What should my board / workflow / governance setup look like for my use-case?"*

A curated set of **community governance templates** (for support, growth, manufacturing, etc.) would give users ready-made starting points and encourage contributions from people using Satya in the wild.

Task
----

Introduce a templates gallery with:

1. **Template directory**
- Add `templates/` at the repo root
- Store templates in JSON/YAML/TOML describing recommended columns, statuses, labels, and logging patterns

2. **Initial templates**
- `customer_support_guardrails`
- `lead_research_agent_flow`
- `manufacturing_qc_agent`

3. **Docs**
- A small guide on how to "apply" a template (using SDK or direct file initialization)
- A short description of each template and when to use it

Implementation Steps
--------------------

- [ ] Create `templates/` directory and a `templates/README.md` that defines the template schema
- [ ] Add at least 2–3 initial templates representing different domains
- [ ] Add a "Governance Templates" section to the main `README.md`
- [ ] Optionally, add screenshots / GIFs of boards using these templates

Resources
---------

- • Existing example project (#161) to see how Satya is typically used
- • Dashboard UI/columns to match template structures

Why This Matters
----------------

Governance templates reduce the "blank page" problem for new users and create a natural way for community members to share and discuss how they use Satya in real-world environments.
