fix(cli): use CLI version instead of stale .env tag

Nikolay Samokhvalovrequested to merge
claude/fix-cli-version-tag into main

Summary

  • CLI now uses its own version (pkg.version) instead of reading stale PGAI_TAG from existing .env files
  • Fixes issue where old .env with PGAI_TAG=beta caused Docker image not found errors
  • Registry and password settings from .env are still preserved

Test plan

  • Run bunx postgresai mon local-install with an existing .env containing an old tag
  • Verify the CLI uses the correct version matching Docker Hub images
