fix(cron): Run now now actually runs + markdown rendering in install sheet

Two fixes chained from manually testing site-status-checker v1.1.0.

---

Cron Run now was a no-op when the Hermes gateway scheduler wasn't
already running. `hermes cron run <id>` only marks a job as due on
the next scheduler tick — it doesn't execute. During dev or right
after install (gateway stopped, as the logs the user pasted showed),
the user's click resulted in nothing happening: job queued, tick
never comes, zero agent sessions, zero output, dashboard never
updates. Exactly the failure mode they hit.

Fix: CronViewModel.runNow now calls `hermes cron run <id>` followed
by `hermes cron tick` after a short delay. `tick` runs all due jobs
once and exits — so the just-queued job actually executes, and
exits cleanly whether the scheduler is running or not. Redundant
(not duplicative) when the gateway is live. The user sees a status
message whether it succeeded or failed instead of silent nothing.

---

Markdown rendering in install-sheet screens. Template READMEs,
manifest descriptions, field help text, and cron prompts all
reasonably contain markdown — but the install preview sheet was
rendering everything as plain text, so `[Create one](https://…)`
would appear verbatim instead of as a link, `# Site Status Checker`
as a literal pound sign, etc.

New Features/Templates/Views/TemplateMarkdown.swift — a tiny,
dependency-free markdown renderer scoped to what template authors
actually write:
- Headings (#..######) → larger bold Text with vertical spacing
- Bullet and numbered lists → hanging-indent rows with •/1. prefix
- Fenced code blocks (```) → monospaced with quaternary background
- Paragraphs → regular Text, with inline formatting via SwiftUI's
  built-in AttributedString(markdown:) so **bold**, *italic*,
  `code`, and [links](urls) work
- Blank lines separate blocks

Two entry points: `TemplateMarkdown.render(_ source:)` returns a
View for multi-block content (README preview), and
`TemplateMarkdown.inlineText(_ source:)` returns a Text for
one-line strings where block structure doesn't apply (field
descriptions, manifest tagline).

Wired into:
- TemplateInstallSheet.readmeSection — was plain Text(readme), now
  renders the full README with structure.
- TemplateInstallSheet.manifestHeader description — inline-only
  (taglines rarely have block structure).
- TemplateInstallSheet.cronSection — new DisclosureGroup per cron
  job exposes the full prompt with markdown rendering. Users can
  now verify what the installer will register with Hermes before
  clicking Install. {{PROJECT_DIR}} / {{TEMPLATE_ID}} tokens show
  unresolved here; they get substituted when the installer calls
  hermes cron create.
- TemplateConfigSheet field descriptions — inline markdown so
  `[Create a token](https://...)`-style links render as real links.

Not a full CommonMark implementation — no tables, no blockquotes,
no images, no HTML passthrough. Those can evolve as templates need
them. Safe with untrusted input: never executes scripts or renders
raw HTML.

Scope stays tight: 57/57 Swift tests + 24/24 Python tests still pass.
No new tests for the markdown helper itself — rendering is visual,
hard to unit-test meaningfully without snapshot-testing infra, and
the surface is small enough that changes would be caught by the
visual regression of any template install.
