v0.4.24

• scripts/station_snap_sweep.R measures what NewGraphEnvironment/fwapg#41's fwa_indexpoint() rework changes on wet_station_snap()'s path (#127). It does not migrate the database: it tries the migration inside a transaction that is rolled back, through the internal wet_pg_trial(). Over HYDAT 2026-07-17's 490 stations only 08KD006's snap moves, to the upper segment at the vertex it is tied on (watershed 8483126 → 7713002, accepted either way). fwa_locatealong() places every candidate measure (114 missed before, 110 of them at stream heads), and two picked catchments that came back empty or raised an error come back. Live tests pin four cases. They skip on an older database, run against the migration under WET_FWAPG_TRIAL, and fail under WET_FWAPG_CURRENT=true. The report is data/checks/station_snap_sweep_20260717.txt. The shipped stations file and fit stay as they are until the next HYDAT release's refit.
