v0.1.4 — Citizen.com as 5th detection source

Waze remains gated behind 2025/2026 reCAPTCHA on live-map; added Citizen
as a working alternative for police-presence signal. Citizen pulls from
911 + scanner traffic, returns rich incident data (lat/lon, timestamp,
severity level, responding precinct, title), and has no auth or
rate-limit gating.

New scan/CitizenClient.kt:
  - GET /api/incident/trending (bbox query → list of incident ids)
  - GET /api/incident/{id}      (full detail per id)
  - Sealed TrendingResult so the scanner can surface 4xx via SourceHealth.

New scan/CitizenScanner.kt:
  - 60s poll interval, 30-min freshness window
  - Per-id detail cache for the lifetime of a start/stop cycle —
    incidents are immutable, so each is fetched at most once per session
  - Title regex filter: drops pure fire/medical events that don't imply
    police presence; retains them when the title also names police action
  - Submits to the shared DetectionStore as DetectionSource.CITIZEN

ConfidenceEngine.scoreCitizen:
  - Base 55 (matches the old W_WAZE_POLICE weight)
  - +5 if level >= 2 (Citizen's own severity)
  - +5 if title contains police-action keyword (police/officer/arrest/
    swat/tactical/raid/pursuit/stop/search warrant)

Settings: new citizenEnabled toggle (default on); UI row in
SettingsScreen. SourceHealth has a new flow for CITIZEN. DetectionService
starts the scanner alongside the others when location is available.

Continued investigation of Waze / Google Maps police APIs:
  - Waze SDK (hewliyang/waze-traffic-api): wraps the same blocked endpoint
  - ddd/google_maps reverse-engineering: locations only, no incidents
  - Google Maps Platform: no public incidents API (just displays Waze data internally)
  - TomTom Traffic Incidents: traffic-only, no police presence
  - Waze for Cities partner feed: real but requires being a city/police agency

versionCode 4 → 5, versionName 0.1.3 → 0.1.4.
