 fix(client): classify discover outcome at source, not at the error type (#1133) 
`ClientLifecycleMode::Auto` only fell back from `server/discover` on
`-32601`, so legacy servers that reject the probe with other codes
(`-32600`, `-32602`, implementation-defined errors) failed to connect
even though `initialize` would have succeeded.

The previous attempt (indicates_legacy_server) classified the failure
after the fact by reverse-engineering the error type. This rewrite moves
the classification into `discover_startup` itself, where the full context
(request id, response correlation, transport state) is still available.

`discover_startup` now returns `DiscoverOutcome`: `Modern` on success,
`Legacy(error)` when the probe received a complete, correlated JSON-RPC
error whose code is not a modern-era rejection. Every other failure
becomes `Err`, so `Auto` simply matches the outcome — no methods on
`ClientInitializeError`, no downcast, no transport-specific types
leaking into the generic lifecycle layer.

Additional fixes that fall out naturally:

- Response correlation is now checked in `expect_response` for both
  success and error branches. Previously error responses skipped id
  correlation entirely. A new `UncorrelatedErrorResponse` variant
  surfaces responses that cannot be tied to the request.

- When both discover and the legacy fallback fail, a
  `LegacyFallbackFailed` compound error preserves both phases instead
  of discarding the discover error.

Fixes #1040.
