Removes the legacy YAML-based simple template system that provided
bug/epic/feature templates for --from-template flag on bd create.
Removed:
- cmd/bd/templates/bug.yaml, epic.yaml, feature.yaml
- Template struct and all YAML loading functions in template.go
- --from-template flag from bd create command
- template_security_test.go (tested removed functions)
- YAML template tests from template_test.go
The Beads template system remains (epics with "template" label,
instantiated via bd template instantiate with variable substitution).
