Remove support for the legacy .beads/nodb_prefix.txt file and use
the cleaner config.yaml approach exclusively for setting the issue
prefix. This simplifies the configuration system and makes it more
consistent.
Changes:
- Remove nodb_prefix.txt creation in cmd/bd/init.go
- Remove nodb_prefix.txt check in cmd/bd/nodb.go detectPrefix()
- Update error message to recommend config.yaml instead
- Update documentation to reflect config.yaml-only approach
New prefix detection order for --no-db mode:
1. issue-prefix in config.yaml (if set)
2. Common prefix from existing issues (if all share same prefix)
3. Current directory name (fallback)
Users should now set the prefix in .beads/config.yaml:
issue-prefix: "myproject"
