agentydragon: refine developer-agent scaffolding and task guidance

- create-task-worktree.sh: load developer-agent prompt from prompts/developer.md

- prompts/developer.md: require populating blank Implementation section

- tasks/task-template.md: require high-level plan in blank Implementation placeholders

- tasks/17-sandbox-precommit-permission-error.md: add task stub for sandbox pre-commit PermissionError

 Before making any changes, read the task definition in `agentydragon/tasks/` and note that its **Status** and **Implementation** sections are placeholders.
 
 After reviewing, update the task’s **Status** to "In progress" and fill in the **Implementation** section with your planned approach.
+If the **Implementation** section is blank or does not describe your intended design and steps, populate it with a concise high‑level plan before proceeding.
 Then proceed directly to implement the full functionality in the codebase as a single atomic unit—regardless of how many components are involved, do not split the work into separate sub-steps or pause to ask whether to decompose it.
 
 Do not pause to seek user confirmation after editing the Markdown;

+title: Sandbox Pre-commit Permission Error
+status: Not started
+summary: Pre-commit hooks fail in sandbox due to inability to lock user gitconfig.
+goal: |
+  Investigate and resolve pre-commit setup failures in sandbox environments caused by permission errors on ~/.gitconfig so that pre-commit checks can run reliably within agent worktrees.
+---
+
+> *This task addresses scaffolding/setup for Agent worktrees.*
+
+## Acceptance Criteria
+
+- Pre-commit hooks detect sandbox environment and skip or override gitconfig locking.
+- Documentation in scaffold guides is updated to note pre-commit limitations and workarounds.
+- Verification steps demonstrate pre-commit hooks succeeding in sandbox without modifying user gitconfig.

+## Implementation

+
+## Notes
+
+- The sandbox prevents locking ~/.gitconfig, leading to PermissionError.
+- Consider configuring pre-commit to use a repo-local config or skip locking by passing `--config` or setting `PRE_COMMIT_HOME`.
