Subject: [PATCH] fix: fix: disinto init fails when projects/<name>.toml
 already exists in repo (#559)

When projects/<name>.toml already exists (e.g. committed from another box),
skip TOML generation and continue with remaining setup steps (clone repo,
create labels, install cron). Reads repo_root and branch from the existing
TOML. If --repo-root flag differs from TOML value, prompts to update it.
