Alan Wizemann a686f8824e feat(templates): hackernews-digest template + dogfooding test harness ...

First pass of the dogfooding-templates initiative. Each pre-release cycle
ships one new official `.scarftemplate` and uses installing/exercising
that template as the regression test. v1 lands the harness scaffolding
plus the first template under it.

- HackerNews Daily Digest template (`templates/awizemann/hackernews-digest/`):
  config-driven (min_score / max_items / topics) cron-only template.
  No secrets — keeps the harness minimal until the fake-Keychain shim
  lands. Bundle validates against `tools/build-catalog.py`; entry added
  to `templates/catalog.json`.
- `SCARF_HERMES_HOME` env-var override at `HermesProfileResolver` —
  the seam every Layer-B test relies on to drive Scarf against an
  isolated Hermes home. Bypasses cache + active_profile lookup; rejects
  relative paths. 5 unit tests + 3 ServerContext integration tests.
- `TestModeFlags.shared.isTestMode` — reads `--scarf-test-mode` once
  from `CommandLine.arguments`. Wiring only; gating sites (Sparkle,
  capability probe, first-run walkthrough) land as Layer-B exercises
  them.
- Layer A (`scarf/scarfTests/TemplateE2ETests.swift`): parses + plans
  the shipped HN bundle the way the app does at install time;
  asserts manifest, config schema, dashboard widgets, and cron prompt
  contract. Mirrors the existing site-status-checker coverage.
- Layer B scaffold (`scarf/scarfUITests/TemplateInstallUITests.swift`):
  proves the launch-arg + env-var plumbing reaches Scarf. Full install
  click-through deferred until fixture-Hermes-home and accessibility
  IDs land.

Wiki pages added separately on the `.wiki-worktree` branch:
- `Template-Ideas.md` — backlog of 9 v1-feasible templates +
  full-spec v3 epic for Project-Site-as-Living-Surface (eBay listings
  use case).
- `Test-Harness.md` — contributor guide for extending the harness.

Verification: scarfTests 124/124, ScarfCore 220/220, new Layer A 3/3,
Layer B scaffold 1/1, build-catalog.py + its 28 unit tests all green.
