Align route path /containers with sidebar label "Agent runs"

[MathurAditya724]

Problem

The sidebar navigation label says "Agent runs" but the URL path is /containers. This creates confusion when sharing URLs or reading the address bar — the URL says "containers" but the UI says "Agent runs."

Affected Files

• apps/server/src/components/layout.tsx:42 — nav item: { title: "Agent runs", url: "/containers", icon: Robot }
• apps/server/src/client/App.tsx:29-31 — routes registered as /containers, /containers/detail, /containers/:entityKey
• apps/server/src/client/pages/sessions.tsx:165 — page title: <h1>Agent runs</h1>

Context

The URL was presumably the original naming when the feature was called "containers." The label was updated to "Agent runs" but the route path was not, likely to avoid breaking existing bookmarks or links.

Expected Fix

Option A (rename routes):

1. Change all /containers routes to /runs or /agent-runs in App.tsx
2. Add a redirect from /containers/* to /runs/* for backward compatibility
3. Update all <Link> and navigate() calls throughout the app
4. Update the nav item URL in layout.tsx

Option B (minimal — add redirect only):

1. Keep /containers as the canonical route
2. Add /runs or /agent-runs as an alias that redirects to /containers
3. This preserves backward compatibility while giving a cleaner URL to share

Option C (rename label back):

1. If "containers" is the correct technical term, rename the sidebar label back to "Containers"
2. This is the simplest fix but loses the user-friendly "Agent runs" label

Impact

Low — This is a naming consistency issue. The mismatch is confusing when sharing URLs verbally or in documentation, but does not affect functionality.

opened #213 — renamed the /containers UI routes to /runs so the address bar matches the "Agent runs" sidebar label, with a redirect from legacy /containers/* links for backward compatibility (Option A). backend api paths are untouched. ready for review.
