rlwilliamson-dev ffa5595fff feat(rain): nowcast enhancements (amounts, capitals, snow/ice, !snow, probability, changeover) + tests
Builds on the merged rain/snow nowcast (#193): ten enhancements plus
end-to-end, proactive, and live-smoke test coverage. All new behavior is
config-gated or additive, so existing deployments are unaffected by default.

Enhancements
- Precip amount estimate "(est 0.2 in)" on the command and the proactive push;
  snow shown as real depth (Open-Meteo snowfall, cm); freezing rain tagged "in ice".
- Bare country / US state resolves to its capital with a heads-up
  (self-contained modules/region_capitals.py; no pycountry/us dependency).
- join_location() dedupes "Spain, Spain" / city-states.
- !snow alias + neutral !nowcast; each looks for its own precip family across
  the window, else falls back with a "No snow, but rain ..." cross-type line.
- Keyword-aware help (help rain / help snow).
- Precip probability shown "(..., 70%)"; the proactive incoming alert is gated
  to >= [Weather_Service] rain_nowcast_min_probability (default 50).
- Rain<->snow changeover line when the window holds both families.
- Borderline temperature tag (30-38F).
- Short-lived series cache shared by the command and the proactive poll.

Tests
- test_rain_command_e2e.py: drives RainCommand.execute() end to end and asserts
  the exact rendered reply across dry/incoming/raining, snow depth, cross-type
  mismatch, changeover, ice, temp tag, region capitals, config toggles, DM
  budget, and keyword-aware help.
- test_rain_proactive_e2e.py: drives Weather_Service._check_rain_nowcast() for
  the probability gate, snow depth, ending notice, and once-per-episode dedup.
- test_rain_live_smoke.py: opt-in (RAIN_LIVE_SMOKE=1) live Open-Meteo check for
  upstream schema drift; skipped in CI.
- Shared scaffolding in tests/unit/_rain_harness.py.

New config: [Rain_Command] show_amount/amount_unit/show_probability/show_temp/
cache_seconds/zip_city_lookup; [Weather_Service] rain_nowcast_min_probability/
rain_nowcast_cache_seconds/rain_nowcast_show_amount/rain_nowcast_amount_unit.
ruff + mypy clean.
