test(cli): bump timeouts and skip slow FS-heavy suites

Raise per-test timeout to 30s in extension and provider-settings suites
where parallel FS load (or worker-pool starvation) can push pure-sync
tests past vitest's 5s default. Skip the fn pi extension and agent-export
suites whose coverage is duplicated by command-level tests but cost ~62s
and ~3.3s respectively on every run.
