fix(test): switch workspace runner to vitest 4 \projects\ field

The workspace-level \`pnpm test:run\` (which fulldeploy.sh runs as a
gate) was failing with \`localStorage is not defined\` on the new
src/web tests. Two intertwined causes:

1. vitest 4 deprecated \`vitest.workspace.ts\`. The file was being
   silently ignored, so per-package configs (cli, mcpd, mcplocal)
   weren't being honored under workspace mode either — the root
   config was being used for all of them.

2. With the root config in charge, src/web/tests ran with the default
   Node environment, no \`localStorage\` global, so the api wrapper's
   test setup blew up.

Fix:
- Move workspace projects into the root \`vitest.config.ts\` under the
  new \`projects\` array (the vitest 4 replacement).
- Add a proper \`src/web/vitest.config.ts\` (vitest 4 doesn't auto-pick
  up vite.config.ts as a test config in workspace mode, even though
  per-package \`pnpm --filter\` does).
- Exclude \`src/web/tests/**\` from the root-level include so we don't
  double-run them under the wrong env.

After: \`pnpm test:run\` runs 1999/1999 across 149 files (was 1992/1996
with 4 web failures). Per-package runs unchanged.
