feat(templates): ship awizemann/template-author skill bundle

A new .scarftemplate in the public catalog whose only content is
a Hermes skill that teaches an agent how to scaffold a new
Scarf-compatible project — dashboard, optional configuration
schema, optional cron job, AGENTS.md — from a short conversational
interview. Scaffolded projects are usable locally and cleanly
exportable as .scarftemplate bundles later.

The skill itself (~400 lines of structured markdown at
skills/scarf-template-author/SKILL.md) covers:

- When to invoke vs. when to answer inline
- The on-disk project shape Scarf expects
- A 5-question interview flow
- Full widget catalog (all 7 widget types) with JSON shapes
- Config schema design + hard invariants (no defaults on secrets,
  `contents.config` must match field count, etc.)
- Cron-job design including the {{PROJECT_DIR}} gotcha
- Step-by-step file writing (dashboard, manifest, AGENTS.md, README)
- Testing + catalog validation instructions
- Common pitfalls + source-of-truth references

Delivered as a .scarftemplate so the install flow's normal
safeguards apply: preview sheet shows one project + one skill
+ zero cron jobs + no config step, uninstall drops both the
project dir and the namespaced skill folder via the existing
lock-file mechanism.

Scope per user sign-off: blank-slate / fully conversational for
v1. Pre-baked archetypes (`monitor`, `dev-dashboard`, etc.) are
deferred to v1.1 pending real usage data on what shapes users
actually ask for.

New Swift test exercises the bundle through the installer's
plan builder — asserts manifest shape, that the skill lands at
~/.hermes/skills/templates/awizemann-template-author/scarf-template-author/SKILL.md,
and that no-config templates correctly skip the manifest cache.
58/58 Swift tests pass; 24/24 Python tests pass.
