Raise default run timeout to 1h, allow per-model override

[yannrichet-asnr]

FZ_RUN_TIMEOUT's default changes from 600s (10min) to 3600s (1h). Models can now set their own "timeout" entry (int seconds) to override this default; None/null or 0 disables the timeout entirely for that model. An explicit timeout= argument to fzr()/fzc() still takes precedence over both.
