…iltering Split Loki time ranges into small chunks (default 5s) processed by a configurable thread pool (default 8 workers), replacing the old approach of splitting into N segments equal to the thread count. This dramatically reduces per-request load and avoids timeouts on large time ranges. Add server-side namespace filtering by injecting LogQL line filters (e.g. |= "\"namespace\":\"argocd\"") when -n/--namespace is used with --from loki, so Loki skips irrelevant log lines before sending them. Chunk size auto-scales to 5m when namespace filters are active to reduce HTTP round-trip overhead. Add graceful Ctrl+C handling during Loki fetches -- cancels pending chunks and continues with partial results. The TUI header shows a yellow "Partial results (interrupted)" badge. New CLI flags: --loki-chunk, --loki-timeout. Progress indicator now shows percentage. TUI header shows total load time.

Summary
-n/--namespaceis used with--from loki, injects LogQL line filters (e.g.|= "\"namespace\":\"argocd\"") so Loki skips irrelevant lines before sending. Chunk size auto-scales to 5m when filters are active.--loki-chunk(max time window per request),--loki-timeout(per-request HTTP timeout).Test plan
--since 2mcompletes in seconds (was 10s+)--since 4h -n argocdcompletes fast with server-side filtering--loki-chunkand--loki-timeoutflags work as documented
