chore: replace uuid dependency with node:crypto randomUUID

[matt-evervault]

What changed

Removed the direct uuid npm dependency and replaced its only usage with randomUUID from node:crypto (built-in, no dependency needed).

• e2e/outboundRelay.test.js: const { v4 } = require('uuid') → const { randomUUID } = require('node:crypto'); v4() → randomUUID() (CJS, matching the file's existing module system).
• package.json: removed "uuid": "^8.1.0" from dependencies. (@types/uuid was not present.)
• package-lock.json: regenerated with npm install --package-lock-only --ignore-scripts. The uuid entry now remains only as a transitive dev dependency (via istanbul-lib-processinfo, used by the nyc coverage tooling) — it is no longer a direct/production dependency.

Unmigrated

None. The single usage was v4(), which maps directly to randomUUID(). No v1/v3/v5/NIL/parse/stringify/validate/version usages were found.

Lockfile status

Updated successfully. --ignore-scripts was required because the prepare (husky install) script is unavailable in this environment; the dependency-tree changes themselves resolved cleanly.
