fix: Landing page #agents-all section not responding

[JeremyDev87]

Purpose

Fix the broken #agents-all anchor on the landing page at https://codingbuddy.jeremy-winchester.com/ko#agents-all — clicking it produces no visible action or scroll.

Changes

• apps/landing-page/widgets/AgentsShowcase/ — Fix anchor target or scroll behavior for #agents-all
• apps/landing-page/src/app/[locale]/ — Verify agents parallel route renders correctly

Acceptance Criteria

• Navigating to /#agents-all scrolls to or reveals the full agents section
• All 31 agents are displayed correctly
• Works across /ko and /en locales
• Existing tests pass
• Can be merged independently

Technical Details

Exact Changes

1. Investigate apps/landing-page/widgets/AgentsShowcase/ for scroll/anchor behavior
2. Check if #agents-all has a corresponding id="agents-all" element in the DOM
3. Verify the agents parallel route at apps/landing-page/src/app/[locale]/@agents/ renders correctly
4. Fix either:
   • Missing id attribute on the agents section container
   • JavaScript scroll handler not triggering
   • Parallel route not mounting the full agents list

Steps

1. Run landing page locally and inspect #agents-all anchor behavior
2. Check DOM for matching element IDs
3. Review AgentsShowcase component for "show all" toggle or pagination logic
4. Fix anchor target and verify smooth scroll behavior
5. Test across /ko and /en locales

Background

URL: https://codingbuddy.jeremy-winchester.com/ko#agents-all
The agents section exists but the #agents-all anchor does not trigger any visible action (no scroll, no filter change, no expansion).
