Pico Transit v0.2.6-pre

Debug-signed APK attached for sideload testing (see README's "Getting it onto a real Light Phone III" section).

Highlights since v0.2.3

• Select Run — for CTA 'L' trains and MBTA Green Line, whose live vehicles show up as a "Closest match" rather than a certain trip match. A stop-by-stop view lets a rider tap the live vehicle they're on directly, plus a quick Next/Previous stepper on Trip Detail.
• Fixed a "running 1400+ minutes early" bug on trips that cross midnight — a real gap in how several shared schedule queries handled GTFS's "transit day" convention.
• Fixed implausible live ETAs from ordinal fuzzy-run matching (an inherently approximate technique) — a wildly-off match now suppresses its status/row instead of displaying a nonsensical time.
• Direction labels ("Northbound"/"Southbound", etc.) were silently dropped almost everywhere except the direction picker — now shown correctly on Upcoming Arrivals, Trip Detail, and Connections.
• Stations list opens straight to arrivals — a plain tap now jumps to live upcoming arrivals instead of the platform map (on by default, Settings toggle).
• Locked to portrait — the app no longer rotates to landscape.
• CARTO map tiles now route through pico-transit-proxy with a real API key, server-side only.
