+`data-raw/study_area_run.sh` pre-flight bug fix exposed by v0.41.1's `--schema=` flag. The pre-flight check for the bcfp reference view was looking in `$SCHEMA.streams_vw_bcfp` (the override-able persist schema), but the bcfp reference is hard-coded to `fresh.streams_vw_bcfp` in `R/lnk_compare_mapping_code.R:78` — it's a constant comparison reference, not a per-run output. The coincidence held while `$SCHEMA` was always `"fresh"`; the new flag exposed the latent bug. Now the pre-flight always checks `fresh.streams_vw_bcfp`, independent of `$SCHEMA`.

 `data-raw/study_area_run.sh` gains a `--schema=<persist-schema>` flag for side-by-side bundle compares. Without the flag, behaviour is unchanged (config's YAML `pipeline$schema` default). With the flag, the driver exports `LNK_SCHEMA` so all per-WSG R scripts (`wsg_run_one.R`, `wsg_recompute_one.R`, `study_area_compare.R`) override `cfg$pipeline$schema` at runtime. The propagation works through SSH to cyphers too (each remote shell exports `LNK_SCHEMA` before its WSG loop). Use case: `--config=default --schema=fresh_default` lets a default-config run land in `fresh_default` without clobbering an earlier `--config=bcfishpass` baseline in `fresh`. Empty `--schema=` value errors loudly rather than silently falling through to the YAML default. Live-validated on ADMS (2.2 min, 11 species habitat tables landed in `fresh_default`, `fresh` untouched).
