feat: redesign runner list controls and add collapsible groups

[fortrel]

Summary

• Replace the flat red/green stop-start icons with monochrome icons in a circular button, and fix runner label badges so they no longer wrap mid-word — they now flow onto additional lines as needed instead of being clipped.
• Make each repo/org group header in the runner list tappable to collapse/expand its runners, with an animated chevron indicator.
• Add a dismiss (×) button to the update-available banner so it can be hidden without installing; it reappears automatically if a newer version becomes available.
• Fix Makefile's run and app targets, which referenced stale binary paths/names (.build/debug/MacRunner and .build/release/MacRunner) that no longer matched the package's actual product name (mac-runner) or swift build's multi-arch output location, and were failing for local development builds.

Test plan

• swift build succeeds
• swift test — 105/105 tests pass
• make app builds a working .app bundle
• Verified button, label-wrapping, collapse/expand, and update-banner dismiss behavior via isolated SwiftUI ImageRenderer snapshots (no Screen Recording/Accessibility permission available in this environment to drive the live popover)
