A terminal pane that has ever run an agent keeps polling the OS process table for completion detection even while HIDDEN. The cadence (750ms active / 2000ms idle) did not depend on visibility, so a backgrounded pane forked a `ps`-scan every ~750ms purely to keep the process-exit backstop alive — wasting idle CPU, especially on shared SSH relays. Follow-up to #6288 / PR #6667 (merged), which deduped scans WITHIN a poll tick via a 500ms-TTL snapshot cache. This attacks the orthogonal axis: the number of ticks a hidden pane runs. Hidden panes now poll at a 3s cadence (HIDDEN_POLL_INTERVAL_MS). This is safe because the process poll is only a BACKSTOP: the primary completion signals — Orca-managed agent hooks (observeHookStatus, push via IPC) and xterm title changes (observeTitle) — are event-driven and fire regardless of poll cadence or visibility. Only a non-hooked agent with no recognizable completion title relies solely on the poll; for that case worst-case hidden completion-notification latency rises to ~2x3s (~6s, repeat-idle-sample) from ~2x750ms. Visible-pane cadence is unchanged (750ms). Becoming visible re-arms the slow hidden timer at full cadence immediately, so switching back to a throttled pane is not sluggish (scheduleNextPoll previously no-oped while any timer was pending). Measured inspection calls over 60s: hidden 78->20 (-74%); visible 78->78. Co-authored-by: Orca <help@stably.ai>
