- admin_welcome.html: update subtitle, description, placeholder cheatsheet
(drop tables/metrics/marketplaces/sync_interval; add user-null note and
security note). Textarea initial value is now empty (no default template
to show). Preview pane uses innerHTML (HTML output). refreshStatus sets
editor to empty when no override. Preview pane styled as light surface.
Reset modal copy updated (no banner shown, not "OSS-shipped template").
- config/claude_md_template.txt: deleted (markdown template is gone;
default is now no banner).
- docs/agent-setup-prompt.md: rewritten for variant C — describes the
/setup banner, smaller placeholder table, security/sanitization notes,
anonymous-user guard, example HTML snippet.
Rename the welcome prompt editor from /admin/welcome to /admin/agent-prompt
and update all UI labels to "Agent Setup Prompt". API endpoint URLs are
unchanged (PUT/GET/DELETE /api/admin/welcome-template, GET /api/welcome).
- Nav menu: "Welcome prompt" → "Agent Setup Prompt", href updated
- Page title and h2 updated in admin_welcome.html
- Error message hint in app/api/welcome.py updated to /admin/agent-prompt
- Dashboard: replace inline <details> preview of _claude_setup_instructions
with a simple link to /setup (Task C)
- docs/welcome-template.md renamed to docs/agent-setup-prompt.md; internal
references to /admin/welcome updated
- OpenAPI snapshot path updated
- Tests updated to reflect new route and removed inline preview
