chore: biome auto-format pass (resolve persistent dirty-tree noise)

These files had been showing as modified in every dev session — biome's
canonical formatting (line-length collapses, import sort, type-modifier
placement) didn't match the committed state. No semantic changes.
Committing now so the working tree stays clean across sessions.
