Default client RPC waits to 60 seconds (#1789)

* fix(client): wait longer for session responses

* fix(client): default RPC waits to sixty seconds

* fix(app): preserve detached stream scroll on delayed history

Code drift: longer client RPC waits let delayed timeline responses arrive after a user scroll-away, so web stream anchoring must not reattach on transient scroll-top resets.

Restore the 15s connect deadline and leave app initialization slack above the default 60s session RPC wait.

* fix(client): keep helper waits within caller deadlines

Review fix: the 60s default session RPC wait leaked into wait previews and waitForAgentUpsert helper fetches. Bound those helper RPCs to the caller deadline or a short best-effort preview timeout, and allow small scroll ranges to reattach at bottom.

* fix(client): respect caller timeout budgets

* fix(cli): keep diagnostic probes responsive

* Refactor daemon client request options

* Preserve daemon client legacy overloads
