Fix status output expectations

[codeaholicguy]

Fixes #235

Summary:

• Align status rendering colors and labels with the shared status style behavior without adding new util files.
• Reconcile the human overall counts with the visible Checks table, including info rows.
• Keep JSON shapes unchanged while routing JSON output through ui.text and preserving absolute paths in service output.
• Shorten home-relative paths only in human output and show a dim explanation when no executable agents are visible.

Validation:

• npm ci
• cd packages/agent-manager && npm run build
• cd packages/channel-connector && npm run build
• cd packages/memory && npm run build
• cd packages/cli && npx vitest run
• cd packages/cli && npx tsc --noEmit
• cd packages/cli && npx oxlint src
• npx prettier --write packages/cli/src/commands/status/render.ts packages/cli/src/services/status/status.service.ts packages/cli/src/tests/commands/status.test.ts packages/cli/src/tests/services/status/status.service.test.ts
• npm run lint
• npm run test
