v0.7.0 — transit_route: TRA↔Taipei-Metro multi-modal routing

v0.7.0 — transit_route: TRA↔Taipei-Metro multi-modal routing (Stage 2)

New MCP tool transit_route(from, to, depart_after?) — the first tool that routes a journey across modes (台鐵 ↔ 台北捷運). Stage 2 of the (B) routing engine north-star (臺灣版 NAVITIME).

Added

• transit_route — time-anchored multi-leg composition over a curated interchange registry. TRA legs reuse the timetable + live TrainLiveBoard delay (source: live/scheduled); metro legs use expected-wait headway/2 at the metro-entry band (source: frequency — TDX metro has frequency, not per-vehicle departure phase). Cross-system transfers only at curated interchanges (台北車站 / 板橋 / 南港 / 松山, IDs probed from live TDX). Endpoints resolve across both systems; same-name metro platforms collapse into one logical station; a vague/multi-station name → matches; no route or TRA-timetable outage → routes:[] + note (empty ≠ error). Tool count 23 → 24.
• Reuses both existing routers unchanged — rail_route (Stage 1) and metro_find_route are untouched.

Verification

• 158 offline tests, 0 failures (MultimodalRouter / InterchangeRegistry / TransitTools executor + 23→24 JSON-RPC smoke).
• Live: transit_route(中壢 → 西門) → TRA 自強 1136 中壢 08:03 → 臺北 08:57, transfer @ 台北車站 (walk 5), 板南線 台北車站 → 西門, arrive 09:09 (66 min, 1 transfer).

Roadmap

Stage 1 (v0.6.0) = TRA time-dependent. Stage 2 (this release) = TRA↔TRTC multi-modal. Stage 3 (future) = unified multi-modal core + bus + fuller live feeds. Accuracy is bounded by TDX data shape, not the algorithm (see CLAUDE.md North Star).
