perf(tests): replace real network ops with mock infrastructure

Browse Source 
- Add centralized mock infrastructure in tests/mocks/:
  - mock-fetch.ts: Bun native fetch interception
  - mock-http-server.ts: Fake server responses (no ports)
  - fixtures/responses.ts: Preset response constants
  - types.ts: Mock type definitions

- Refactor https-tunnel-proxy.test.ts:
  - Remove TEST_CERT constant (~50 lines)
  - Remove real HTTPS server creation
  - Use invalid hosts for error path testing
  - 26/26 tests pass in ~430ms

- Refactor remote-token-uploader.test.ts:
  - Replace 7 real HTTP servers with mockFetch
  - Reduce from 422 to 289 lines
  - 18/18 tests pass in ~120ms

- Add global test timeout (10s) in bunfig.toml

Test suite: 10+ min → 14 seconds
