fix(site): give each agent its own install path, Claude Code first (#435)

The landing hero's copy box was `git clone ...` and install step 1 was
"Clone the repo" for everyone, so a Claude Code user, who needs no
clone, was pointed at a 30 MB+ checkout of gallery and showcase assets.

- The hero copy box shows (and copies) the Claude Code command,
  `/plugin marketplace add TMHSDigital/Blender-Developer-Tools@plugin-dist`.
  It is site.json `heroCommand` (prompt label `heroPrompt`), falling back
  to `git clone` for the shared template.
- Install steps are per agent: Claude Code (two commands), Cursor (the
  0.3 MB plugin-dist local plugin), other agents (clone and copy skills/
  into the agent's skills folder), then snippets and templates. The
  heading, now `installHeading`, says "No clone needed."

Closes #371
