agent: improve make-task-issue with efficient GraphQL and correct API usage

Requirement:
Improve make-task-issue command to use efficient project lookup and correct GitHub API
field names for issue type assignment.

Implementation:
- Updated to use GraphQL repository.projectsV2 query for efficient project lookup
- Changed from listing all org projects to querying only repository-linked projects
- Fixed issue type API field from 'issue_type' to 'type' with capitalized values
- Added GraphQL query example and implementation notes

+   - Use GitHub API via gh CLI: `gh api repos/{owner}/{repo}/issues/{issue-number} -X PATCH -f type='Task'`

+   - Issue types are an organization-level feature and may not be available in all repositories
 
 5. **Add to GitHub Project**:
    - After issue creation, add the issue to the repository's linked GitHub Project
-   - First, get the project linked to the repository:
-     * Use: `gh project list --owner {owner}` to find projects
-     * Or query linked projects: `gh api repos/{owner}/{repo}/projects`
-   - Then add the issue to the project:
+   - Get the project linked to the repository using GraphQL (most efficient):
+     ```bash
+     gh api graphql -f query='
+     {
+       repository(owner: "{owner}", name: "{repo}") {
+         projectsV2(first: 1) {
+           nodes {
+             id
+             number
+             title
+           }
+         }
+       }
+     }'
+     ```
+   - Extract the project number from the response
+   - Add the issue to the project:
      * Use: `gh project item-add {project-number} --owner {owner} --url {issue-url}`
-     * Or use GraphQL API for more control
    - If no project is linked or command fails, show informative message but don't fail issue creation
+   - Note: This approach is more efficient than listing all organization projects as it queries only repository-linked projects
