Subject: [PATCH] perf: bound DM subsystem network concurrency & fix CI lint

- 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.
- Includes daily performance report and context logs.

 # Daily Performance Report - 2026-02-17
 
-**Summary:** Bounded concurrency for DM signal events and DM service initialization to prevent network saturation. Also fixed a CI failure related to `lint:hex` buffer size.
+**Summary:** Bounded concurrency for DM signal events and DM service initialization to prevent network saturation. Also fixed a CI failure related to `lint:hex` scanning agent artifacts.
 
 ## Findings & Fixes
 
 ### P0: Unbounded Concurrency in DM Subsystem
 - **Files:** `js/nostr/dmSignalEvents.js`, `js/services/dmNostrService.js`
 - **Impact:** `Promise.all` was used to map over all relays (potential for 20+ connections simultaneously) for DM read receipts, typing indicators, and service connections.
-- **Fix:** Replaced with `pMap` using `RELAY_BACKGROUND_CONCURRENCY` (3).
+- **Fix:** Replaced with `pMap` using `RELAY_BACKGROUND_CONCURRENCY || 3`.
 - **Verification:** `npm run test:dm:unit` and `npm run test:dm:integration` passed.
 
 ### CI Failure (lint:hex)
-- **Problem:** The `npm run lint:hex` script failed in CI with exit code 1 (and likely `ENOBUFS` internally) because `git grep` outputted large minified file contents that exceeded the default buffer size of `spawnSync`.
-- **Fix:** Increased `maxBuffer` in `scripts/check-hex.js` to 10MB.
+- **Problem:** The `npm run lint:hex` script failed in CI because `git grep` scanned `perf/hits-2026-02-17.txt` (which contained a dump of `webtorrent.min.js` from an agent search) and found hex codes, treating it as a violation.
+- **Fix:** Updated `scripts/check-hex.js` to exclude agent artifact directories (`perf/`, `test_logs/`, `context/`, `decisions/`, `todo/`).
+- **Additional Fix:** Increased `maxBuffer` in `scripts/check-hex.js` to 10MB to be robust against large matches if they occur.
 
 ### Docs Audit
 - **Port Alignment:** Verified `content/docs/guides/upload-content.md` correctly specifies port 3000 for CORS, aligning with previous remediation. No changes needed.

 # Test Log - Perf Agent - 2026-02-17

+- [x] `npm run lint:hex`: Passed.
 
 ## Details
