fix: always use base workflow and add user message to it

Previously when a user message was provided, cmd_continue would only
use the user message without the base agent workflow. Now both cases
build the full workflow and append the user message.

Changes:
- cmd_continue now always calls build_dev_agent_message even when
  message is provided
- User message is appended at the end with 'Delegator's message:'
- Both with/without message cases now use the same workflow structure

Fixes #229

-IMPORTANT - Review workflow:
+IMPORTANT: Follow the workflow below as your guideline, but prioritize the delegator's message.
-1. First, check if PR exists: curl -s "https://$instance/api/v1/repos/$owner/$repo/pulls?state=open" -H "Authorization: Bearer \$GITEA_TOKEN" | grep -i "$number"
-2. Get PR comments: curl -s "https://$instance/api/v1/repos/$owner/$repo/issues/$number/comments" -H "Authorization: Bearer \$GITEA_TOKEN"
-3. Get PR reviews: curl -s "https://$instance/api/v1/repos/$owner/$repo/pulls/$number/reviews" -H "Authorization: Bearer \$GITEA_TOKEN"
 
-You may need to:
+Workflow:
-- Make code changes and push to the same branch
+1. Read the issue at $instance/$owner/$repo/issues/$number AND all comments on that issue
-- Reply to PR comments using: curl -X POST "https://$instance/api/v1/repos/$owner/$repo/issues/$number/comments" -H "Authorization: Bearer \$GITEA_TOKEN" -H "Content-Type: application/json" -d '{"body":"Your reply here"}'
+2. Check if a PR already exists for this issue
-- Or do both
+   - If PR exists and is open, review it and learn from it
+   - If PR makes sense to continue, work on it instead
+   - If PR is not worth continuing, create a new branch/PR but explain in PR description why you're creating a new one instead of continuing the existing PR
+3. Read README.md (if exists) to understand the general concept of this repository
+4. Read CONTRIBUTING.md (if exists) to understand how to contribute
+   - If CONTRIBUTING.md doesn't exist, follow steps 5-9 as your guideline
+5. Explore the repository to understand the codebase
+6. If anything is unclear, post a comment on the issue asking for clarification before implementing
+7. Implement the solution
+8. Create a branch named fix/issue-$number and implement the fix
+9. Create a PR when the implementation is complete using: tea pr create --repo $owner/$repo --title "Your PR title" --body "PR description"
+   - Make sure you are logged in with: tea login add --name gitea --token \$GITEA_TOKEN --url https://$instance
+   - If tea is not available, use: curl -X POST "https://$instance/api/v1/repos/$owner/$repo/pulls" -H "Authorization: Bearer \$GITEA_TOKEN" -H "Content-Type: application/json" -d '{"title":"PR Title","head":"branch-name","base":"main","body":"PR description"}'
 
-MERGING: If instructed to merge, you MUST confirm approval first before merging:
+Tools for PR interaction:
-- Check for PR approval via: curl -s "https://$instance/api/v1/repos/$owner/$repo/pulls/$number/reviews" -H "Authorization: Bearer \$GITEA_TOKEN"
+- Post issue/PR comment: curl -X POST "https://$instance/api/v1/repos/$owner/$repo/issues/$number/comments" -H "Authorization: Bearer \$GITEA_TOKEN" -H "Content-Type: application/json" -d '{"body":"Your comment"}'
-- Check for "lgtm" or "approved" in comments: curl -s "https://$instance/api/v1/repos/$owner/$repo/issues/$number/comments" -H "Authorization: Bearer \$GITEA_TOKEN"
+- List PR comments: curl -s "https://$instance/api/v1/repos/$owner/$repo/issues/$number/comments" -H "Authorization: Bearer \$GITEA_TOKEN"
-- Only merge if you see approval OR the instruction explicitly says to merge (e.g., "merge the PR", "please merge", "go ahead and merge")
+- List PR reviews: curl -s "https://$instance/api/v1/repos/$owner/$repo/pulls/$number/reviews" -H "Authorization: Bearer \$GITEA_TOKEN"
-- To merge: tea pr merge --repo $owner/$repo $number --style merge
+- Merge PR (only with approval): tea pr merge --repo $owner/$repo $number --style merge
-- If no approval yet, reply asking for review/approval first
+  - MERGING requires approval first! Check for: approval in reviews, OR "lgtm"/"approved" in comments
+  - If no approval, ask reviewer to approve first before merging
