* Fix: Use template when creating new issues

(Description, Requirements, Success Criteria) are now included in
all newly created issues.

+# Make template work
+
+## Description
+
+The `gi create` command is not using the `.issues/template.md` file when creating new issues. New issues are created with minimal content instead of the structured template that includes Description, Requirements, and Success Criteria sections.
+
+## Current Behavior
+
+When running `gi create`, new issues are created with only:
+- YAML frontmatter (id, assignee, labels, created, updated)
+- A simple title heading
+- Empty content
+
+## Expected Behavior
+
+New issues should be created based on `.issues/template.md`, which includes:
+- YAML frontmatter (with appropriate fields populated)
+- Title heading
+- Description section with placeholder text
+- Requirements section with example bullet points
+- Success Criteria section with checkboxes
+
+## Steps to Reproduce
+
+1. Run `gi create` and enter an issue title
+2. Open the newly created issue file
+3. Observe that the file does not contain the template sections
+
+## Impact
+
+Users must manually add common sections (Description, Requirements, Success Criteria) to each new issue, reducing productivity and consistency across issues.
+
+## Success Criteria
+
+- [ ] `gi create` command reads `.issues/template.md` when creating new issues
+- [ ] Template sections (Description, Requirements, Success Criteria) appear in new issues
+- [ ] YAML frontmatter fields are properly populated (id, timestamps, etc.)
+- [ ] Title from user input replaces "Issue Title" placeholder in template
