v10.0.0

10.0.0 (2026-07-20)

⚠ BREAKING CHANGES

• (multimodal): three breaking changes shipped earlier in 9.94.x-9.95.x
  are now documented in docs/MIGRATION.md: (1) multimodal file/CSV
  processing is fail-loud since v9.94.6 (throws ErrorFactory.fileProcessingFailed
  /csvProcessingFailed instead of log-and-skip), (2) MessageContent
  (src/lib/types/multimodal.ts) dropped its open index signature since
  v9.94.6 (closed shape, TS2353 on unknown fields), (3) BatchCommandArgs.file
  was renamed to .promptsFile since v9.95.1. No further behavior changes to
  these three in this commit — this commit only adds the migration doc.

Bug Fixes

• (multimodal): close post-merge review gaps (batch parity, pdf limits, url-secret redaction, supervisor identity) (1956f4a)
