fix: ensure directories exist before writing adapter scripts

- Create env directory in copy script functions before writing
- Fixes initialization errors for Parakeet, Canary, and Sortformer adapters
- Update Makefile to use web/project-site for website commands
- Add build target to Makefile for building Scriberr binary
