Find utility providers when someone is moving to a Texas address or setting up utilities at a new home. Covers nine utility types: electricity, internet, gas, water, sewer (city wastewater), trash, propane (rural / off-grid alternative to natural gas), septic (rural / off-grid alternative to city sewer), and home security. Use when the user says things like 'I'm moving to Houston next month', 'I just bought a house in Austin and need to set up power', 'what's the cheapest electricity in Dallas', 'who provides internet at this apartment in San Antonio', or rural-address questions like 'I'm moving to a ranch in Bandera, what do I do for gas and sewer' (answer: propane + septic). Returns available providers with a classified plan type (fixed / free_nights / solar_buyback / 100_renewable / etc.) and whether the cheapest plan is rental-friendly; pass tenancy='rent' to prefer short-contract plans or tenancy='own' to surface solar-buyback options. Caveats: (1) water results may include many PWS rows within a ZIP's county radius — filter to `primaryForZip === true` for the single canonical provider likely to serve the parcel. (2) Trash providers in TX suburbs include `metadata.contractedHauler` (Republic Services / Community Waste Disposal / Waste Management / Best Trash / Texas Disposal Systems / Waste Connections) — surface this so users know the actual pickup company in addition to the city dept. (3) Propane and septic appear at all TX ZIPs including urban ones; in cities with natural gas + city sewer, treat them as alternative options rather than primary. (4) Sewer is city wastewater (urban); septic is on-site (rural / unincorporated). (5) For electricity in Texas, results are filtered to retail providers (REPs) that actually serve the address's TDU — Oncor (DFW), CenterPoint (Houston), AEP TX Central (Corpus / RGV), AEP TX North (Abilene / San Angelo), or TNMP (scattered). Agents do not need to filter by TDU themselves. The TDU slug is exposed as `tdu` per electricity provider so agents can explain to the user why the list is shorter than they might expect (e.g. ~20 REPs at a Houston address vs. ~47 statewide). At municipal-utility ZIPs (Austin Energy, CPS Energy, El Paso Electric) the only electricity provider returned is the muni; REPs cannot sell power there.
