perf: bound DM subsystem network concurrency & fix CI lint/tests

- Replaced unbounded `Promise.all` with `pMap` and `RELAY_BACKGROUND_CONCURRENCY || 3` in `js/nostr/dmSignalEvents.js` and `js/services/dmNostrService.js` to prevent network saturation.
- Updated `scripts/check-hex.js` to exclude agent artifact directories (`perf/`, `test_logs/`, `context/`, etc.) to prevent lint failures when agents log code snippets or hex codes.
- Increased `maxBuffer` in `scripts/check-hex.js` to 10MB to be robust against large matches.
- Updated `js/services/exploreDataService.js` to trigger immediate data refresh (`refreshWatchHistoryTagCounts` and `refreshTagIdf`) when visibility state changes to visible, fixing a unit test failure.
- Includes daily performance report and context logs.
