chore: refresh GitNexus stats + drop stale tsbuildinfo

GitNexus analyze --embeddings after the alerts-inbox-redesign branch
brought the graph to 8780 symbols / 22753 relationships (was 8527/22174
in AGENTS.md and 8603/22281 in CLAUDE.md). The stat-header drift between
AGENTS.md and CLAUDE.md is an artifact of separate reindexes — both now
in sync.

ui/tsconfig.app.tsbuildinfo was a stale tsc incremental-build cache
that shouldn't be tracked.
