v0.6.0 — rail_route: TRA time-dependent routing

v0.6.0 — rail_route: TRA time-dependent routing (Stage 1 of the routing engine)

New MCP tool rail_route(from, to, depart_after?, system) — TRA time-dependent O/D routing (#7). It routes over the real DailyTrainTimetable (per-train departure/arrival times) with a connection-scan earliest-arrival search, then applies live TrainLiveBoard delays so the chosen itinerary reflects current conditions: a delayed train can lose to a later on-time one. This is Stage 1 of a staged time-dependent, live-aware transit routing engine (MCP-native, Taiwan-deep).

Added

• rail_route returns legs[] (train_no, from/to station, dep/arr times, delay_min, source: live | scheduled) + arrival_time + duration_min. TRA-only (the only mode with both a public timetable and a live delay board); distinct from rail_find_trains (which lists all trains). Tool count 22 → 23.
• Reuses existing RailODFare/RailStopTime/RailLiveTrain models + existing registry endpoints (both arrive v3-wrapped; decoded via TDXDecode.list). Graceful when the timetable (HTTP 500/empty) or live board is unavailable — empty + note, never a crash; missing live data → all legs scheduled.

Verification

• 143 offline tests green, incl. TimetableRouterTests (the live-delay-changes-the-chosen-train case) + executor graceful-degradation tests.
• Live: rail_route(臺北 1000 → 臺中 3300, now) → train 111, 臺北 08:00 → 臺中 09:49, 109 min, source: live.

Roadmap (#7)

Stage 1 (this release) = TRA. Stage 2 = headway modes (metro/bus) as synthesized connections. Stage 3 = unified multi-modal CSA/RAPTOR + full live feed.
