feat(perf): establish baseline and identify async patterns

- Scanned codebase for `setInterval`, `Promise.all`, and other async patterns.
- Generated `reports/performance/hits-2026-02-20.json`.
- Identified potential unbounded concurrency in `src/services/memory`.
- Created daily performance report.
- Updated run artifacts and memory.

+
+## Goal
+Establish a performance baseline and identify P0/P1 issues using search patterns.
+
+## Scope
+- Scan codebase for performance-critical patterns (intervals, workers, etc.).
+- Generate hits report.
+- Audit /content documentation if needed (deferred to analysis).
+
+## Constraints
+- Minimal changes for baseline establishment.
+- Must run search script.
+
+## Assumptions
+- This is the first run (or treated as such for baseline).
