Commands such as offckb fiber status print a DEP0040 warning during startup on recent Node.js versions. The node-fetch 2 dependency chain imports Node's deprecated built-in punycode from both whatwg-url 5.0.0 and tr46 0.0.3.

Patch both imports to punycode/ and declare the userland dependency with pnpm package extensions, preserving the current fetch and HTTP proxy implementation. Includes a patch changeset.

Validation on the latest develop baseline:

• Frozen dependency install and pnpm build passed.

• pnpm test:ci --runInBand: 58 suites passed; 560 tests passed, 7 skipped.

• pnpm lint passed with one existing no-explicit-any warning in src/node/install.ts.

• Built CLI --version, --help, and isolated fiber status passed on Node 20.12.0, 22.19.0, and 24.8.0 with empty stderr, after clearing warning-suppression environment variables and enabling --pending-deprecation --throw-deprecation.

• Internationalized hostname conversion through the legacy URL parser passed.

• Added an automated regression test that builds the CLI and starts it with --pending-deprecation --throw-deprecation, clearing warning-suppression environment variables and asserting successful startup with empty stderr.
