What: the `initOnSessionStart` setup-schema description and the Honcho docs page
now state that in `recallMode: tools` the eager init runs synchronously during
agent construction, that it should stay false for Desktop or a local Honcho that
may be down, and that `timeout` in honcho.json caps each SDK call (both keys
added to the Full Config Reference table).
Why: #51492 reports Desktop `session.resume` / `prompt.submit` timeouts when a
local Honcho is down with `initOnSessionStart: true`. The synchronous eager path
is intentional design (#51562 was closed for that reason:
"ready-before-first-tool-call semantics"), so the fix for users is knowing the
trade-off and the two knobs that bound it.
