Fixes 257 typecheck errors surfaced after the upstream merge:
- Update imports to new module paths after upstream PR #24554 removed
module barrel files (@/config, @/session, @/util, etc.) and PR #24309
renamed @opencode-ai/shared to @opencode-ai/core.
- Migrate loadMode to use Info.zod.safeParse for consistency with
loadAgents and ConfigCommand (unblocks KilocodeConfig.handleInvalid).
- Drop removed Npm.outdated mock from tests.
- Add missing Config.defaultLayer to bash-permission-metadata test runtime.
- Fix Tips component signature (kilocode drops upstream's 'connected' prop).
- Fix toast.tsx undefined 'duration' reference (should be toastOptions.duration).
- Move filesystem-containment test from deleted shared package to core.
Remove the standalone `packages/util` and `packages/server` workspace
packages, migrating all imports across app, kilo-ui, opencode, and ui
to use `@opencode-ai/shared/util/*` paths instead. Also fix the
VITE_KILO_CHANNEL env variable name in the type declaration and add a
null guard in the titlebar channel badge rendering.
