chore: fix vitest standalone configs and update package description (#11865)

* chore: fix vitest standalone configs and update package description

- vitest.live.config.ts and vitest.e2e.config.ts now extend root config
- Inherits testTimeout (120s), resolve.alias, pool, setupFiles, excludes
- ui/vitest.node.config.ts gets explicit 120s timeout
- package.json description updated for multi-channel AI gateway
- Removed unused src/utils/time-format.ts

* chore: filter inherited excludes in live/e2e vitest configs

* refactor: dedupe GroupPolicy/DmPolicy in extensions
