Bare `mock.module('axios', () => ({ default: { stubs } }))` is
process-global last-write-wins and drops `axios.create`, `request`,
`isAxiosError`, etc. that real consumers need. In CI's alphabetical
file order, that produces dozens of polluted failures (AgentsPlatformView,
schedule API, memory-stores API, etc.) that don't reproduce on WSL2.
Introduce `tests/mocks/axios.ts` with `setupAxiosMock()` — `require('axios')`
inside the factory, spread real shape, route each verb through a per-suite
`useStubs` flag. beforeAll flips on, afterAll flips off; the spread
fall-through eliminates cross-file leakage.
Refactored 12 axios mockers in tests/, plus the bare `@anthropic/ink` mocks
in ultrareviewCommand and onboarding suites (same pollution pattern broke
AgentsPlatformView's Box/Text rendering).
Verified: 5339/5345 tests pass locally; remaining 6 failures are
pre-existing isolation issues unrelated to this change.
