fix(tls): pivot per-runner TLS to path-routing on single subdomain
The per-subdomain approach (*.mcp.buildmymcpserver.com) failed at the
Cloudflare edge — Universal SSL only covers ONE-level wildcards, so the
TLS handshake on slug.mcp.buildmymcpserver.com hits SSL alert 40
handshake_failure. The two paths to fix that (CF Advanced Cert Manager
at $10/mo, or a Let's-Encrypt wildcard via DNS-01 with certbot) both
trade either money or ops for the URL aesthetic.

Pivot to path-routing on the single subdomain mcp.buildmymcpserver.com,
which IS covered by free Universal SSL. publicUrl format changes from
  https://<slug>.mcp.buildmymcpserver.com  →  https://mcp.buildmymcpserver.com/<slug>
No recurring cost, works with the existing CF setup, MCP clients don't
care about the URL shape (it comes from the wizard's install snippet).

Code changes:
- generator/lib/deploy.ts:
    * publicUrl computed as `${MCP_DOMAIN}/${slug}` instead of `${slug}.${MCP_DOMAIN}`
    * writeRunnerMapEntry writes one-line nginx snippet:
        if ($bmm_slug = "<slug>") { set $bmm_port <port>; }
      (was: a map-entry pair "<slug>.<MCP_DOMAIN> <port>;")
- setup-runner-tls.sh:
    * nginx vhost is now single server_name mcp.buildmymcpserver.com
    * regex location captures (?<bmm_slug>...)(?<bmm_path>/.*)?
    * includes runner-map.combined inside the location block so the
      generated if-snippets set $bmm_port; unknown slug → 404
    * proxy_pass strips the slug prefix: /<slug>/foo → 127.0.0.1:port/foo
    * Prereq docs updated: just A-record for mcp (no wildcard needed),
      same Origin CA cert reused
    * Added /health endpoint at vhost root for monitoring

Systemd watcher + map dir + volume mounts unchanged — same file paths,
just different snippet content. Re-running setup-runner-tls.sh on the
host overwrites the wildcard vhost with the new path-based one.
