feat(274): route data for the transect; lyric fixes the transect exposed

Building the transect visualisation (Song274Transect) is what exposed problems in the lyric and its index: syncing nodes to the lyric showed 紅葉山橋 lighting up although it is not on this road (it is on R452), 下福山橋 and オロロップ橋 sitting at the wrong km, and lines timed against the wrong stretch. They were fixed upstream in the wiki (ncmr-songs 7af0f48, "274: drop 紅葉山橋, fix オロロップ橋 and 下福山橋, re-timed lyric"), and the lyric deliverables here follow. 274.lrc — byte-identical copy of the wiki LRC at 7af0f48: 紅葉山橋 removed; 紅楓橋 through 楓信号場 re-timed (1:35.24–1:55.54) with 夕張市楓 at 1:45.77; 登川トンネル at 2:05.23 and its section end at 2:06.62; 稲里トンネル's section end at 4:25.27. 下福山橋 and オロロップ橋 keep their timing; their km were corrected in the roster and index. 274.srt — regenerated with scripts/lrc2srt.py, 116 cues. 274.ass — events follow the LRC: district headers as transparent_title spanning their section, 東に続く as transparent_lyrics_jp, spacers as empty events, the final line held 5 s. The Aegisub header and all 17 styles are untouched. 117 events -> 116. route/ — copied from novoyuuparosk-wiki/ncmr-songs wip/274, where it is generated; read-only here, and its README says so. src/song-274/data.ts loads 274-route.json, 274-lookup.csv and 274-lyrics-index.csv, plus the two approach stubs: 274-route-west.json (always drawn as covered) and 274-route-east.json (painted after 東に続く). Also carries the district bands, the GeoJSON and the reference page. The route shapes are single clean polylines: no second-carriageway points in the divided sections, km strictly increasing. Verified: all 116 ASS events and SRT cues match the LRC's order, text and timestamps; every sung node in the index joins to the roster at matching km.
