The V25 table has duplicate column names (Backtranslation x3, Rationale x3).
The dict-based parser collapsed these — only the last value survived (Option 3's
"N/A"), causing all BT/rationale fields to be "N/A" in the output Excel.
Fixed by switching to positional list-based parsing instead of dicts.
Also adds per-job model selection (Sonnet 4.6 / Opus 4.6) through the full
stack: DB column, API schema, job wizard UI dropdown, pipeline contracts, and
LLM client with model-aware cost tracking. Includes Alembic migration.
Updated help page and README to reflect single-agent pipeline, multi-TM
selection, flat locale grid, model selector, and linguistic summary.
