fix(init): allow fresh clones with JSONL to run bd init (bd-4h9)

Previously, bd init blocked when JSONL existed with issues but no database,
telling users to run 'bd doctor --fix'. But doctor --fix just ran bd migrate
which requires an existing database - creating a circular dependency.

Now:
- bd init allows fresh clones (JSONL exists, no database) to proceed
- bd init creates the database and imports from JSONL automatically
- bd doctor --fix runs bd init (not migrate) when there's no database
