feat(insights): AI surfaces its own observations from full network state

Adds a parallel LLM path that reviews the whole org snapshot — Preseem
APs, SNMP signals, backhaul, agents, and the insight types the rules
already covered — and emits novel observations as ai_observation
insights (source=ai). Existing rule-based insights and per-insight
enrichment continue unchanged.

- lib/towerops/llm/network_snapshot.ex builds the bounded snapshot
- lib/towerops/llm/network_insight_prompt.ex builds the prompt and
  parses the LLM's JSON observations array
- lib/towerops/workers/ai_network_insight_worker.ex runs nightly at
  03:30 UTC (after the rule pass + per-insight enrichment) and on
  the superuser regenerate button
- preseem/insight.ex extends @valid_types with "ai_observation" and
  @valid_sources with "ai"
- insights_live/index.ex includes the new worker in the regen list
  and adds an "AI" source badge style

Bumps the SnmpKit Manager timeout-options test threshold from 500ms
to 3000ms (was flaking on loaded dev machines), and scopes
list_unenriched_insights/1 assertion in insights_test:573 to the
test's org so cross-suite leaks don't fail the count.

+feat(insights): AI now generates its own observations from full network state
+  Previously the LLM was only used to enrich existing rule-based insights
+  (per-insight summary/action). Now there's a parallel path:
+  Towerops.Workers.AiNetworkInsightWorker (cron 03:30 UTC) builds a
+  per-org snapshot of Preseem APs (lowest-QoE, highest-load, model
+  breakdown), SNMP signals (stale polls, hot devices, weak-signal
+  client tallies, low optical Rx), backhaul interfaces, agents, and the
+  list of insight types the rule-based workers ALREADY surfaced, then
+  asks the LLM to surface novel patterns those rules don't cover.
+  Findings persist as Insight rows with type=ai_observation, source=ai.
+  - lib/towerops/llm/network_snapshot.ex (new) — token-bounded snapshot
+  - lib/towerops/llm/network_insight_prompt.ex (new) — prompt + parser
+  - lib/towerops/workers/ai_network_insight_worker.ex (new)
+  - lib/towerops/preseem/insight.ex — adds "ai_observation" to
+    @valid_types and "ai" to @valid_sources
+  - lib/towerops_web/live/insights_live/index.ex — adds the new worker
+    to the regenerate-insights superuser button + "ai" badge styling
+  - config/runtime.exs — cron entry "30 3 * * *"
+  - test/towerops/llm/network_snapshot_test.exs (new)
+  - test/towerops/llm/network_insight_prompt_test.exs (new)
+  - test/towerops/workers/ai_network_insight_worker_test.exs (new)
+  - test/towerops_web/live/insights_live_events_test.exs — assert the

+  You are a senior WISP/network-operations engineer reviewing a snapshot
+  of one organization's network state. Your job: surface concrete,
+  actionable observations that a rule-based monitoring system would
+  likely miss — patterns, correlations across signals, or anomalies that
+  emerge only when looking at the network as a whole.
+
+  You are given:
+  - totals (devices, sites, APs, agents)
+  - preseem (worst APs by QoE, highest-load APs, model breakdown)
+  - snmp (stale polls, hot devices, weak-signal client tallies, low optical Rx)
+  - backhaul (interfaces with configured capacity)
+  - gaiia (subscriber-mapping reconciliation findings)
+  - agents (online/offline counts)
+  - existing_insights (insight types the rule-based system has ALREADY surfaced)
+
+  Hard rules:
+  1. Do NOT restate findings already in `existing_insights` — those are
+     covered. Look for what's NOT there.
+  2. Only reference values present in the snapshot. Do not invent device
+     names, scores, or counts.
+  3. Each observation must be concrete and actionable. "QoE could be
+     better" is not actionable; "AP North at QoE 42 vs fleet ePMP 3000
+     average 78 — investigate alignment or interference" is.
+  4. Prefer cross-signal correlations: a hot device that's also showing
+     low QoE; a site where many APs share a model and all underperform;
+     a backhaul whose downstream APs all degrade together.
+  5. If nothing meaningful is present, return an empty observations list.
+

+  {"observations": [
+    {"title": "...", "description": "...", "urgency": "critical"|"warning"|"info",

+2026-05-10 — AI now spots patterns rule-based monitoring misses
+* The AI now reviews your network as a whole — looking at QoE, signal, capacity, agents, reconciliation findings, and the insights already surfaced — and adds its own observations when it spots something the rule-based monitors don't already cover
+* AI-generated observations appear alongside existing insights, tagged with an "AI" source badge so you can tell where each finding came from
+* Existing rule-based insights still run and are still individually summarized — the AI layer only adds; it doesn't replace
+* Useful for cross-signal patterns like "this site's APs all share a model AND all underperform" or "this hot device is also the one with the worst QoE"
+
 2026-05-09 — Smarter recommendations + AI-generated insight summaries
 * New recommendation: low optical Rx power on fiber transceivers, with the standard cleanup-then-replace troubleshooting ladder
 * New recommendation: upstream degradation — when many of your APs at one site go bad at the same time, the system flags it as an upstream/backhaul problem so you don't waste time chasing per-AP RF symptoms
