Spent the day on a significant refactoring pass. Extracted large modules into smaller, focused files - the verify init command alone went from a monolithic 377 lines down to several purpose-built modules like detectExistingSetup, setupKnip, and installPackage. Did the same for devlog, refactor, and vscode commands.

Added filename convention enforcement via biome, requiring files to use either camelCase or be named index.ts. This prompted renaming several files like devlog.ts → index.ts and fileNameCheck.ts → runFileNameCheck.ts.

Also improved jscpd integration with quieter output and detection of outdated configurations, plus deduplicated package.json reading logic into a shared utility.
