Copilot ae120c916f fix(scrape): skip active stale temps and retry salvage merge

Avoid salvaging export.json while a channel export is still writing
(default: skip temps modified within 120s). Retry truncate+merge once
when merge fails on a quiescent partial temp. Adds active-skip smoke
and ages stale fixture mtime so salvage tests stay deterministic.

fix: Skip active stale temps and retry salvage merge

Problem

salvage_stale_temp_exports can run while a channel export is still writing export.json. The file is truncated/invalid, merge_exports_auto fails, and the temp is retained — but the next incremental pass hits the same race. Observed on KotOR yes_general (221726893064454144): merge fails on ~82MB partial temp while archive stays at 266182 messages (2021 cursor).

Salvage after export completes works (truncated temp → 79529 messages merges to 345711 in ~58s).

Requirements

ID	Requirement
R1	Skip stale temp dirs whose `export.json` was modified within `DCE_STALE_TEMP_MIN_AGE_SECONDS` (default 120)
R2	On merge failure, re-run `salvage_truncated_json` and retry merge once before retaining temp
R3	Log merge retry vs skip-active with distinct messages
R4	Offline smoke: active temp skipped; retry succeeds after simulated truncation
R5	`run-all-smokes.sh` passes

Implementation

scripts/run-discord-scrape.sh — stale_temp_is_active, skip guard, merge retry helper
scripts/tests/run-discord-scrape-smoke.sh — active-temp skip + merge-retry scenarios

Verification

./scripts/tests/run-discord-scrape-smoke.sh
DCE_MIN_FREE_MB=0 ./scripts/run-all-smokes.sh
