test: replaced real timers and sleeps with deterministic test hooks

- Added `providerRetryWait` and `retryWait` hooks to stream/usage options so tests bypass real scheduler delays.
- Parameterized GitHub Copilot poll intervals and Copilot model retry base delay for fast test execution.
- Replaced `Bun.sleep`/`setTimeout` polling loops with `AbortSignal` event listeners in agent session tests.
- Consolidated auth-gateway E2E helpers into a shared `test/helpers` module, eliminating duplicated `checkGatewayAvailable` implementations.
- Migrated credential-disabled tests from SQLite-backed stores to an in-memory store, removing temp-dir lifecycle overhead.
